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.

Thanks Gert & Peter.  I’m going to look into the 9001.  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.
