I have 2 routers connected, can ping each other on the F0/0 interfaces. Each has loopback interfaces which are the only once advertised in BGP (AS1).
Problem: I am not able to ping the loopback addresses.
Any ideas. This should be possible.
router bgp 1
neighbor 184.108.40.206 remote-as 1
neighbor 220.127.116.11 update-source Loopback0
R2#sh run | beg bgp
router bgp 1
neighbor 18.104.22.168 remote-as 1
neighbor 22.214.171.124 update-source Loopback0
The routers can ping each other:
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 126.96.36.199, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 96/140/220 ms
What did I miss?
Debug message from R1:
*Mar 1 06:59:01.918: BGP: 188.8.131.52 active open failed - no route to peer, open a ctive delayed 29293ms (35000ms max, 28% jitter)
What Mike was asking you to do is to establish BGP peering one of two-ways.
1. If you want to use loopback addresses to peer then you need to have a static or another IGP route (not BGP) to the far end loopback address. You would also need to reinstate the 'update-source' command that you removed. You need a config similar to this one;
ip route 184.108.40.206 255.255.255.255 220.127.116.11
ip route 18.104.22.168 255.255.255.255 (next_hop_ip)
2. Your second option is to reconfigure, on both routers, the "neighbor (physical_int_IP_address) remote-as 7000' to the physical interface IP on the far end device. This doesn't need any static/IGP routing as the peering IP addresses are directly connected.
