Hi, Confirm loopback interface reachability first. Ping the other router loopback with the source of your current loopback. If succesful then bgp should esterblish without a problem. If not you will have to do some routing to ensure the loopbacks are reachable.

Please forgive me if I am asking some dump question. I already did iBGP and eBGP neighbor connection, everything alright. I now try to extend to use loopback address to configure bgp neighbors. I can not get it success, the BGP status is "Active" but not "Established" for some reason. The topology is really simple as below, but I currently have no clue what I should modify to make it work. # BGP router in AS 100 router bgp 100 neighbor 2.2.2.2 remote-as 200 neighbor 2.2.2.2 ebgp-multihop 3 neighbor 2.2.2.2 update-source 1.1.1.1 # BGP router in AS 200 router bgp 200 neighbor 1.1.1.1 remote-as 100 neighbor 1.1.1.1 ebgp-multihop 3 neighbor 1.1.1.1 update-source 2.2.2.2 Any thoughts? I will really appreciate any help!! Qing _______________________________________________ Quagga-users mailing list [email protected] https://lists.quagga.net/mailman/listinfo/quagga-users
