are you able to ping each other from either host? ß Yes, Can Ping
May I know is there any network/IGP setup first?
if they are directly connected or correctly routed then no prior work needs to be done.

looks like the problem is not with the bird. Although it looks like both hosts are on the same subnet, but are you able to ping each other from either host?

It'd be more helpful you can provide your `bird.conf` and `birdc show proto all` if all possible.

Dear MO,
Thank you very much for your response.
Yes, I followed the sample to set up the routers but don’t why the peering session between them is not established.

Dear All,
I’m Rae of CUHK. 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?
