I am trying to build full mesh of ATM Pvc's between three sites, the IGP and LDP adjacency comes up between all three locations, but the BGP session is not coming up. I check and don't have the loopback rechability by ping I have these loopback in routing table using ISIS as the IGP, hence BGP not coming up. I can understand that there is some pvc encapsulation issue causing me the reachability problem, But I am unable to get this ATM setup work.
I am getting the error messages: 00:48:01: %ATM-3-FAILCREATEVC: ATM failed to create VC(VCD=16, VPI=1, VCI=37) on Interface ATM2/0, (Cause of the failure: vpi/vci pair already in use) 00:48:21: %ATM-3-FAILCREATEVC: ATM failed to create VC(VCD=20, VPI=1, VCI=38) on Interface ATM2/0, (Cause of the failure: vpi/vci pair already in use) which causes all the trouble, I am missing some basic here, can you help me!!!
