If you disable the adj-rib-out then it will not.

something else is going on. The routes are received but the router chooses to only install one

show ip bgp 10.7.255.33 shows both?
Mark Felder

Mar 01 2018 15:46
no, it only shows the one
and it's also missing from sh ip bgp ipv4 unicast neighbors x.x.x.x received-routes
bizarre because the router log clearly shows it saw it

ah, sounds like you maybe need the adj-rib-out thing ?

in exabgp.conf ? I've set it to both true and false with no change in the results.

when run with -d exabgp will show what it is sending.
so you can know if the route has been sent or not
what version are you using ?
Mark Felder
@feld
Mar 01 2018 15:53
3.4.20
if the route wasn't sent why would the cisco router see it? :) I'll grab some debug output
*see it // log it
