finally, stop the iptables. 2 BIRD routers can establish BGP.

But cannot form BGP with Cisco csr1000v router

Last error: Socket: Connection refused <--

1. can traceroute from cisco router to a BIRD

2. cannot traceroute from the BIRD router to the Cisco router

3. can ping together

4. iptables service is stopped on BIRD

Would you please help.
