OPSF (in this scenario) is easier to set up then BGP...but check out

Re: Redundant BGP for lower cost

[Alex Thurlow]

I have to say that this looks like a nice solution to me, and I've 
definitely had many people point me to OSPF.  One problem is that I've 
never run OSPF before.  Some googling brings of a few results on 
implementation, but can someone recommend a good place to look or a book 
to get to really get it all figured out?


Thanks,
Alex

While you're at it, add extra fans and run the edge systems off solid 
state disks or CF cards.


Or, buy $real hardware.

 Here's my situation:  I have two providers, each handing me
gigabit ethernet.  I'm getting full BGP feeds and handling them
with a Linux/Quagga router.  We max out at about 100kpps, as we're
mostly pushing video which gives us a large packet size.  It works
fine, and I've been happy with it so far.  But, we've gotten to
the point where I want a backup router of some sort in case
something happens to that one, what with the fans and disks that
could fail.  I see a few options.

1. Just set up another Quagga box and use keepalived or some other
HA solution.
2. Buy a Cisco/Juniper/whatever and then have the Quagga box as
backup.
3. I have a 6500 behind the router that's just doing switching.
 Could I have something switch that to static route all traffic to
one of my providers if something happened to the router?  The 6500
has Sup1A with MSFC2 running IOS native.

On the Cisco side, I see that we could probably run a 7200VXR with
NPE-G1 (about $6000 on ebay).  Moving to the Sup720, even used is
probably out of our price range.

What do you guys think I should use here?

If you were to upgrade the 6500 to a Sup720-3bxl or better, it would be a 
far superior platform for handling multiple gigabit ethernet circuits and 
full BGP than the NPE-G1.  Sadly, the sup720 and required power supply and 
fan card upgrades would cost more than that 7200/NPE-G1, but it'll route 
considerably more traffic.  I don't think you're going to get line-rate 
GigE from the G1.  You will with the 6500.

Re: Redundant BGP for lower cost

If you want to keep it cheap, roll out another Quagga edge - one to each
peer. Drop default into OSPF from both edges, iBGP over a GE between them.
If one toasts you'll only lose half your routes for 1s-ish, or however long
you set your OSPF keepalives.

While you're at it, add extra fans and run the edge systems off solid state
disks or CF cards.

Or, buy $real hardware.

Redundant BGP for lower cost

[Alex Thurlow]

Let me preface this by saying that I'm not a full time network admin, 
but we're a small company and I'm the only one handling this.  Our 
budget is also not huge, but we're at the point where extended downtime 
would cost us enough money that we can spend some money to fix the problem.


 Here's my situation:  I have two providers, each handing me gigabit 
ethernet.  I'm getting full BGP feeds and handling them with a 
Linux/Quagga router.  We max out at about 100kpps, as we're mostly 
pushing video which gives us a large packet size.  It works fine, and 
I've been happy with it so far.  But, we've gotten to the point where I 
want a backup router of some sort in case something happens to that one, 
what with the fans and disks that could fail.  I see a few options.


1. Just set up another Quagga box and use keepalived or some other HA 
solution.

2. Buy a Cisco/Juniper/whatever and then have the Quagga box as backup.
3. I have a 6500 behind the router that's just doing switching.  Could I 
have something switch that to static route all traffic to one of my 
providers if something happened to the router?  The 6500 has Sup1A with 
MSFC2 running IOS native.


On the Cisco side, I see that we could probably run a 7200VXR with 
NPE-G1 (about $6000 on ebay).  Moving to the Sup720, even used is 
probably out of our price range.
