Mikrotik OSPF can break older Quagga releases. (Imagestream can use Quagga)
For example,. I recently installed some RB1100s, and my Zebra .94 machines
instantly went into route floods and restarts, and filling log files in a day.
I upgraded to Quagga .12 and all good now. (note: Quagga current release is up
to .18 now.
The week before I had an issue where three OSPF routers were on the same
subnet. (mikrotik being the third) and Instantly made OSPF go haywire. Changed
so two remote OSFPD servers were on their own IP block, and problem solved.
Mikrotik often blaims Quagga for the bug. But then again, tings didn;t crash
until the Mikrotik was injected.
I guess my point is... OSPF is more complicated than some people think. Its to
be expected that different OSPF servers may react differently to certain
network conditions.
But almost always, there is a way to fix it, when one figures out the design
flaw in the configuration, which often is a user issue, more than a
manufacturer issue.
I like Quagga because there is a huge comunity behind it. Easier for me to
support it. But so far my Mikrotik seems to be doing OSPF fine, now that all is
configured properly.

We've had trouble with Imagestream to Mikrotik OSPF. It seems to break itself
every six months or so. Anyone else had to trouble with that?

Imagestream has been very good to us as well. Every bit the "Cisco
experience", but at a fraction of the cost. Reliability has been excellent.
They hum along year after year.

I have used Imagestream routers in what I would consider
carrier situations. Have had Imagestreams in VRRP running multiple BGP full
feeds and Gigs of traffic per second. Not saying it's a do all solution, but
is a serious contender. Add on top the fact you don't need $1000's of dollars
a year for smartnet I am happy. Not saying it's your solution, but definitely
worth looking at.

I would like to ask for help of wireless community.
We have to choose supplier of core router for our WISP projects. I know
technical characteristics and price for core routers from Cisco - 7200 and 7600
series. Although these models have impressive possibilities, their price is
very prohibitive for small/medium projects. Which models of core router do use
in your projects? I would like to get your recommendations, its advantages and
disadvantages. Would like to know some cheap and middle-price options.
It comes down to the feature set you need and the performance required.
Can you share your expected traffic numbers and what features you want to run?
The cisco 7200 is a bit long in the tooth, the 7600 is the way to go
forward. Each can be found on the secondary market for cheap. From a new
device purchase decision, it's hard to beat the Juniper SRX series for smaller
deployments. a $1500 router can handle 300 mbit/s of IP/mpls and firewall in
hardware is hard to beat. The new MX series can handle 80gb/slot and its the
next big competition to the 7600 from cisco. Junos is amazing to work with
compared to IOS too.
However if you do need multiple line rate 10gb/s interfaces, the ALU
7750/7710 should be considered too.
I'd not consider the Imagestream product as it's not a serious carrier
contender. As of two years back they just did not have a product, and bowed
out of an RFP I was forced into running. It's a neat small office router, but
that's all.
Again this is all my opinion :)
