Hi,
I had a weird problem today that I can't explain when I tried to add a peer
(185.22.129.11) to bgpd.
The prefix was accepted, shows up in RIB as valid, installed in FIB according to
bgpctl but kernel could not find a route. Group "liopen" provides a fullview.
OpenBSD-current from May 8th.
I had to restart bgpd for the route to show up.
Any idea what happened ?
rt-grav-02# bgpctl sh fib 193.169.46.0/23
flags: * = valid, B = BGP, C = Connected, S = Static, D = Dynamic
N = BGP Nexthop reachable via this route
r = reject route, b = blackhole route
flags prio destination gateway
*B 48 193.169.46.0/23 185.22.129.11
rt-grav-02# route get 193.169.46.0/23
get net 193.169.46.0/23: not in table
