Hello,
I have the following 3 Hosts. Two of the hosts are in the same subnet. The other one is in another /24.
I want to do iBGP for EVPN via VXLAN with BGP as control layer. Why is the session for the two hosts in the same subnet established but the server in the other subnet is not reached? Firewall and everything looks ok. Port 149/TCP for BGP is open. Any Idea?

nevermind.. I solved the problem via manually setting the routes for the target network.
For example for xxx.xxx.249.15: ip route xxx.xxx.254.0/24 xxx.xxx.249.254
