I have had quite a bit of problems with the early double digits of 3.1x on
the PowerRouter 732 (dual core CPU).

3.13 has been beautiful so far.

Re: [WISPA] How many switches can do RSTP?

[can...@believewireless.net]

The main advantage of Imagestream is that you get their tech support people.
 When I've had problems that I thought were Imagestream related, they helped
point to the Mikrotik server that wasn't doing something right.
Cisco's support is very good as well but much more expensive than
Imagestream.

We have both Mikrotik and Imagestream running BGP and OSPF.  OSPF is
definitely the way to go for internal routing.  It's a much lighter weight
protocol.

OSPF on Mikrotik works and works well, but you have to find the version that
works best with your routers.  For example, one version my work well on
Mikrotik hardware while a different version works better on X86 hardware.

We've also seen different issues with the same Mikrotik OS version on
different X86 hardware.  So, if you are planning to go with Mikrotik,
probably best to go with a vendor that knows the issues.  I've wanted to
look into www.mikrotikrouter.com and their Power Router.

Cisco or ImageStream.  ImageStream is cheaper and offers more
functionality (besides just BGP, I mean).  Perhaps "flexibility" is a
better word than "functionality" in that last sentence, though both are
true.  Either way, I just don't recommend MT as a BGP peer for external.
I have a few customers using it, but their needs are fairly simple as
BGP goes.  For complex BGP implementations, I'd recommend ImageStream or
Cisco (in that order).

Re: [WISPA] How many switches can do RSTP?

[Tom DeReggi]

Well, I can't comment on using BGP on Mikrotik. And there is not a shortage 
of testimonials for reason to use Cisco Switches/Routers.
But I will say, if someone choses not to use Mikrotik for BGP, that does not 
mean that CISCO is the answer for BGP.

Linux has always outperformed Cisco with BGP. Our implentations of Quagga 
99.10 have worked flawlessly for our BGP applications.
It offers... More RAM, More CPU cycles, and that translates to quicker table 
updates, unlimited filter/routemap rules, more BGP sessions per machine, 
etc.
The one router on my network that must be a Linux machine, is my Core 
External BGP servers. Internal in the network, its less important, because 
the load is much less.

Glad to see it works for you.  I have heard a couple other success stories
but Butch's (my Mikrotik prophet) suggestion is to use Cisco for BGP.

Re: [WISPA] How many switches can do RSTP?

BGP is on 42 routers. We have twice as many mikrotiks, but some won't 
get it because they don't need it (due to the nature of their function), 
and there are some we haven't had the spare time to convert away from 
static routes.

We have BGP on our internet uplink too, but that's not MT, and it 
doesn't do dynamic routing with the MT network presently. It can do it, 
we just haven't felt compelled to tinker with that important role.

Internal BGP is pretty light duty compared to Internet BGP; a few 
pages of routes compared to a quarter million routes. V3 MTs propogate 
routing changes very quickly; almost instantly. V2 MTs have a short 
delay for routing changes.

BGP works on all paid or included license levels, which is a plus. We've 
also done BGP for about 8 years on our uplink with Ciscos, which has 
provided me with some initial skills.

Re: [WISPA] How many switches can do RSTP?

[eje]

BGP is more designed for routing application with upstream or downstream 
applications. Of course you can use it internally as well and in that case if 
your not using BGP for upstream you can use any AS number you want. OSPF can be 
used in any network design and is designed for internal routing. You do not at 
all have to be star shaped actually OSPF functions best when not and you are 
"circular" shaped. 
I have used BGP for our internal routing but moved to an OSPF implementation 
and feel it do work better and faster then BGP at least on our network and we 
are neither really stared nor circular in our network configuration.

We are using BGP internally on Mikrotik with good success instead of 
OSPF. I've never done OSPF on it, as my network isn't entirely star 
shaped like OSPF is said to be created for. There is a range of private 
BGP AS numbers for such applications. Each site's router gets an ASN and 
has peering connections to upstream and other connected sites.

Would you mind sharing how many routers you have using BGP and Mikrotik?
I've been told that BGP is only a majority successful.

You are correct.  However, I'd request that you reread what I posted.  I
did not suggest that MPLS was a Cisco specific platform.  My Cisco
statement was a segue to a new, but related, thought.  The idea I
presented was that, while there are opinions that differ from my own,
MPLS offers certain benefits that can be easily accomplished by other
means without making the major network design changes required by MPLS.
My statement was in no way intended to be a "Cisco bash" (Cisco offers
plenty of opportunity for me to do that).

Yes.  I have read the wikipedia entries referenced many times as part of
my own research on MPLS.

Perhaps you misunderstood my point.  Again, I was not suggesting that
MPLS was a Cisco proprietary protocol.  My point was that AT&T is
marketing MPLS very effectively and that they (like cisco does all the
time) are assisting various businesses and agencies in developing RFPs
that include MPLS.  It is THAT behaviour that Cisco (along with
Microsoft, AT&T and a host of other "big boys") that I was referencing
negatively.

Hmm..I may not have done a very good job of explaining myself with
regard to MPLS.  MPLS certainly offers some neat features.  VPLS by
itself is almost worth the struggle to undergo the pain of building and
implementing it in a network.  It does require a rather large network to
be "worthwhile", however from a usability standpoint.  MPLS will ONLY
work within a single administrative domain.  The labels are only unique
within that domain.  Typically, labels (which are used to build paths)
are not shared outside a single network.  Because of this, a smaller
network does not see a lot of benefit from MPLS.  My main point was that
the "most useful" benefits of MPLS (like VPLS for example) can be done
in other ways without the limitations of MPLS (like the requirement for
a single administrative domain or label sharing).  

One thing that ISN'T easily duplicated is the ability to use a route
reflector (specially configured BGP "server") to make VPLS circuits very
easy to deploy and centrally maintain.  The basic functionality provided
by VPLS, however, IS easily duplicated.  An example of this is
Mikrotik's new ability to use PPtP on a bridge.  I can build a network
using this functionality and create a layer 2 bridge without regard to
who owns the transport using this functionality.  Even better, I can
match the 1500 byte MTU that MPLS offers.

I rarely include the specific protocols as part of my proposals unless
it offers a specific benefit or meets a specific need that can't be
matched otherwise.  I understand your point, however, and I do often
tout the benefits brought by my choice of products.  More often that
that, however, I tout the benefits of using MY service more than the
equipment.  ;-)

Re: [WISPA] How many switches can do RSTP?

[Jeff Broadwick]

I'll have to agree with John here.  There certainly is a LOT of hype
surrounding MPLS, and many, if not most, of the people who are demanding it
really don't need it.  Don't mistake that for genuine applications that will
require MPLS.  Point-to-multipoint VPN is just one example.

I agree with much of your thoughts here but the one above does not seem
right to me. I read up on this some to make sure I was not mistaken. MPLS is
supported by many vendors and is being touted by many to be the replacement
for other platforms like ATM. Here is a quote from the Wikipedia article
that Nathan had referenced which I believe substantiates that MPLS is an
open platform supported by multiple vendors:

"It (MPLS) was a Cisco proprietary proposal, and was renamed "Label
Switching". It was handed over to the
IETF<http://en.wikipedia.org/wiki/Internet_Engineering_Task_Force>for
open standardization. The IETF work involved proposals from other vendors,
and development of a consensus protocol that combined features from several
vendors' work."

Obviously Cisco is used by so many that they have pull but they did not keep
MPLS for themselves. By making it an open platform they have taken the high
road I think. Had they not then I would be pissed to have it be part of RFPs
also. Please note that I prefer to use Imagestream and Mikrotik for all of

Re: [WISPA] How many switches can do RSTP?

[Nathan Stooke]

Hello,

Mikrotik all the way.

I take great pride in the fact that we have no Cisco Routers on our
network.  Sure there are issues with firmware releases now and then with MT,
but now that they are on 3.X is has become much much more stable.

Thanks

This is one of the benefits I mentioned.  There are other ways to gain
this benefit, however.  I'm not gonna go through all the possibilities
with what can be done with MPLS and show the comparable option another
way.  The point I was making before was more that MPLS is a new

same benefits in ways that don't require MPLS.  I agree that VPLS is a
"cool" feature that can, for some networks, be a "necessary" feature.
For most, however, MPLS is NOT worth the time and effort necessary to
understand for the benefits gained.

The person who started this thread sounded like he was "searching" for a
technology without defining a need and I was just pointing out that
design goals should come first.

Yes.  I have said for over 2 years that MPLS is more a "marketing ploy"
than a necessary technology.  I remember standing in front of Brad
Belton's office discussing this exact subject.  MPLS is likely to be a
"necessary" item for some JUST to be able to sell the same product.
Cisco does this all the time.  They help corporations and government
entities write up RFQs with requirements that include Cisco specific
capabilities.  Really pisses me off sometimes.  :-)

I'm glad you have MPLS running and working on your network.  Are you
using manually configured tunnels or are you implementing this using a
route reflector?

Re: [WISPA] How many switches can do RSTP?

[Nathan Stooke]

Hello,

We have 3 on another part of our network, but I know you can do
more.  It works really well for our setup.  We are using RSTP so we do not
even loose a ping when it changes over.

However, we do not care much for it.  It does work in the right
instances, but you have a limit as to the number of STP domains you can have
on a switch.  I think our switches limit is 8.

Thanks

Re: [WISPA] How many switches can do RSTP?

[Nathan Stooke]

Hello,

We rolled out MPLS more to get VPLS.  While we have plans to really
utilize the MPLS we really need the VPLS for our clients that needed
transport across our network.  On another note ATT is pushing MPLS
connections to multiple sites instead of their T1 services in our area.
Even though they are really using the T1s for the service and they are
really offering VPLS services.  

We have not really any issues with the MPLS or VPLS.  Of course I
have the best or one of the best network admin's around so he had everything
tested and when we implemented it is was very smooth.

Thanks

While there are some bugs in SOME versions of Mikrotik's RouterOS
releases, it is far from being "too many bugs" to be used.  Of course, I
only have about 200 or so networks that I maintain with only about 2500
routers to base this on

MPLS is not likely to be a "best solution" regardless of the platform
you use.  Like WiMAX, however, MPLS is a new "buzzword" that people will
flock to.  Mikrotik's MPLS implementation is brand new and not one I'd
recommend for anyone at this point.  I have 3 or 4 customers with
networks large enough to gain some benefit from MPLS.  One is attempting
to get it working with some limited success.  

In most cases, you won't really need MPLS to accomplish your design
goals.  So far, I haven't seen you say what you are having trouble with,
just that you have not correctly configured your OSPF implementation
(you said it like it was purely a MT problem, but I doubt that is likely
based on my own experiences).

Re: [WISPA] How many switches can do RSTP?

We are using a routed backbone with Mikrotik's OSPF. We have Mikrotik
working without problems with product from ImageStream, Cisco, and Juniper.
I haven't tried anything MPLS yet, we've been too busy to experiment with
it.

The only troubles I've ran into with Mikrotik OSPF has been the occasional
reboot required when we have a backhaul link flapping constantly, as well as
some problems with some redundant customer routing.  We have several
customers that are paying extra for redundant links, we are giving them a
/30 and installing a Mikrotik router with OSPF running.  We've had a time or
two where our normal traffic would route through their connection instead of
our backbone(not sure why), but that was fixed when we started filtering the
advertised routes.

I don't remember who it was, but about two years ago I visited with a WISP
that was running several thousand customers on a bridged network (STP IIRC).
They were using the MAC dst-nat functionality to forward all broadcasts to
their PPPoE server at one end of the network, they said it was working very
well for them.

Re: [WISPA] How many switches can do RSTP?

[Dennis Burgess - Linktechs.net]

Routed is the way to go. Think of this, the internet is routed, why 
should you not be..

I support hundreds of networks running RouterOS most with dynamic 
routing, with very little issues.

Re: [WISPA] How many switches can do RSTP?

[Nathan Stooke]

Hello,

Yes our core is running MPLS.  We us Mikrotik routers so it does not
coast use a huge amount.  They also have anew virtual router that allows you
to take 1 box and put 2 or more routers on it.  We have a MPLS core router
and a Edge router at each main tower on our ring.  This did save use a about
50% because we did not have to buy the second router.

Thanks

Hi Nathan,

it could be a solution, but:

1) the only product I found interesting it CISCO ME switch with MPLS.
Any other suggestion welcome.
2) cost per site goes really high for the backbone. If we would like to
implement MPLS in each site, it would cost us a fortune.
3) Still wondering about maturity or many MPLS implementations, not sure
the brands that really work and the ones which does not.

Suggestions welcome ;)

P.S. are you using MPLS?

Re: [WISPA] How many switches can do RSTP?

[Paolo Di Francesco]

Mixed 2.9.X/3.X, yes running the "right one" routing pack (it was much
worse with the "stable pack").

1) OSPF default route goes lost time to time, so some nodes get but of
the network
2) sometimes OSPF does not communicate some routes (the neighbor is
there but the route is not appearing, it should be working but it's not)
3) OSPF does not work with BGP Openbgp implementation (default route
goes lost, it looks like mikrotik thing, not nice when the traffic on
the edge is not going anywhere and more or less the whole network is down)
4) memory leakage in some versions, so we have to remind to reboot the
devices time to time
5) other minor bugs here and there (this morning we had a strange thing
the route should be there but the router was not getting it from the
neighbor)

Maybe we are just not lucky or we have too many flapping links.

Re: [WISPA] How many switches can do RSTP?

[eje]

Just curious what issues do you see, what version are you using. Running the 
experimental routing package? Are you using MikroTik only or are you exchanging 
OSPF routing with other devices? I used OSPF and mikotik for a long time and 
except for a few bad revisions it has been rock solid.

Hi Travis

to be honest mikrotik routing is not working well, and we are far from
being happy about the OSPF implementation: too many bugs and lost routes.
So, I would like to move to something more robust. Mikrotik MPLS
implementation looks more at experimental stage and I would not use it
for any reason in any production network. Maybe I am wrong and it's
really stable, so if somebody is using mikrotik-MPLS let us know it!

Thank you.

Re: [WISPA] How many switches can do RSTP?

[Jerry Richardson]

There was a presentation on MikroTik MPLS at Animal Farm that was very
informative.
 
We are not using any MikroTik (yet) however a couple of WIPS operators
that I trust are using it with alot of success.

Mikrotik now supports MPLS. So any routerboard should work fine,

we are routed, but routed has other problems. So I was

If you have that many a routed network would be

Re: [WISPA] How many switches can do RSTP?

[Travis Johnson]

Mikrotik now supports MPLS. So any routerboard should work fine,
depending on how much traffic you need to move.

it could be a solution, but:

1) the only product I found interesting it CISCO ME switch with MPLS.
Any other suggestion welcome.

implement MPLS in each site, it would cost us a fortune.
3) Still wondering about maturity or many MPLS implementations, not sure
the brands that really work and the ones which does not.

Suggestions welcome ;)

P.S. are you using MPLS?

we are routed, but routed has other problems. So I was just wondering
about switched...

Thank you.



  If you have that many a routed network would be much simpler.

Any ideas on the limit of stp devices, though?

Dear All

I am wondering how many switches can be put together in a bridged
environment (via radio-bridges) with the Rapid STP. Just curious because
I did not find anywhere the maximum number and wondering if the backbone
collapse after 10 or 100 or 1000 switches.
Also wondering what do you advice, I know that not all the switches are
the same... (thinking about HP for this application)

Thank you in advance.

[WISPA] How many switches can do RSTP?

[Paolo Di Francesco]

Dear All

I am wondering how many switches can be put together in a bridged
environment (via radio-bridges) with the Rapid STP. Just curious because
I did not find anywhere the maximum number and wondering if the backbone
collapse after 10 or 100 or 1000 switches.
Also wondering what do you advice, I know that not all the switches are
the same... (thinking about HP for this application)

Thank you in advance.
