Hi Qing, The static routes should point to the ip address on the neighboring routers connecting interface.

Conceptually it makes totally sense, although I couldn't get the static routes stuff working. # 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 ip route 1.1.1.0 255.255.255.0 10.0.1.1 # this is the line for static route I added, should it be outside or inside the "router block"? Tried both but neither working # 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 ip route 2.2.2.0 255.255.255.0 10.0.2.2 # same here And here is the outputs for "show ip route" >>> IP Route for node a1 is: Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, A - Babel, > - selected route, * - FIB route C>* MailScanner warning: numerical links are often malicious: 1.1.1.0/24 is directly connected, lo C>* MailScanner warning: numerical links are often malicious: 10.0.0.0/16 is directly connected, a1-eth0 C>* MailScanner warning: numerical links are often malicious: 127.0.0.0/8 is directly connected, lo Here is the outputs for "route -n" mininext> a1 route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.0.0.0 0.0.0.0 255.255.0.0 U 0 0 0 a1-eth0 I tried couple ways to add the static routes, but I still not be able to get it right. Could you please take a look of my config file and point out where is wrong? It could really save some potential hours for me, I really appreciate the help!

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. Regards Hillary K.

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
