[c-nsp] Rec for full-table multi-peer bgp router?

[Jiri Prochazka]

Hi,

we're using 7280SR as the full BGP routing edge with a great success, on 
many POPs. 2-3 full BGP feeds from eBGP neighbors (with VERY complex 
route-maps), a few iBGP peers, sFlow..

The biggest limitation is that it can handle just ~2M routes in RIB so 
you can not receive more than 3 full v4 feeds (now, this will probably 
change, as the code gets better). The switch can technically 
handle/receive more, but Arista says 'we do not recommend this'.

As someone noted, the RIB scales up to ~1.2M, which is enough, for us.

We have been hit by a few quite nasty bugs on this platform, but 
Arista's support guys were always able to find a solution/workaround. 
Actually we have discovered a few new bugs on 7280SR, which were not 
known to Arista.


So, if you're looking for someone who is using this platform as full BGP 
routing edge - we're the (very satisfied) example. We're pushing more 
than 700 Gbps over them.

We have a bunch of Arista in the core doing ospf/ospfv3, the rep there suggested their 7280SR, which is 48 SFP+, 6 QSFP, and they claim it’s stable as a BGP router with limitations of 1.2M ipv4 / 768k ipv6 routes, simultaneously, no picking and choosing like Brocade.  Obviously, it’s good price point, but I’m not sure I’m ready to trust them in an edge router role as I don’t know anyone using them for BGP.  I’m also not sure how long 1.2M ipv4 routes will be good for given we’re already over the half way point to that and the table has been growing regularly after run out.   List is $66k for reference.
