are you able to ping each other from either host? <-- Yes, Can Ping May I know is there any network/IGP setup first?

Although it looks like both hosts are on the same subnet, but are you able to ping each other from either host?

Yes, I followed the sample to set up the routers but don’t why the peering session between them is not established.

We are exploring BIRD router/route server functions. Now I set up 2 BIRD routers to from BGP session between them, seems It can’t form the peering (in active status). Questions: 1. Is there any pre-config need to be set up? (i.e. interface? Internal Subnet?) 2. Would you mind sending me some sample configurations?
