Hi, I have been using Openbgpd on Openbsd from last 3 years without any issue. We are having two upstream providers with full route. Suddenly last week, i observed that our network became unreachable from internet and sometimes fluctuating in terms of reachability. I checked the bgp session using bgpctl show summary which was showing bgp session alive and PrfRcvd(Received prefix) from our peers was fine.
When i tried to ping to both peers WAN IP or any inetrnet ip, it was telling "no route to host". When i connected peers wan ip to standalone system and tried pinging, it was pinging. I was not able to figure out the issue and after 45-60 minutes, automatically everything got rectified and became normal. I am not having any idea about this issue and want to explore to avoid such situations in production environment. Kindly assist. -- Thanks and regards, *Randhir Prakash*
