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
