In this case it was BFD that kicked in – I have BFD only set up for the two route reflectors. Other BGP sessions stayed up. I also got this alert from our Arista 7504: Apr 15 17:37:34 207.32.15.14 (sxct-north-2.sxcy.fbnt.netins.net) Bfd: %BFD-5-INCOMPATIBLE_RX_INTERVAL: Received a BFD rx interval from peer (vrf:default, ip:206.108.255.2 (AS53679-MRS-2.micemn.net) intf:Port-Channel2, srcIp:0.0.0.0, type:normal) of 10 milliseconds, outside of the supported range of 50-60000 milliseconds. (message repeated 3 times in 1.18783e+06 secs) Is Arista falling bit short in this situation, by not supporting 10 msec?

Right now it is setup for broadcast, and multicast, however I am in favor of adding unknown unicast.
