Hi In this case I'd be careful with these features Even though the advantage is that you won't loose the label mappings from the particular neighbor in case the direct link fails as the ldp hellos would be exchanged between the loopbacks and can be routed around the failed link same as the tcp session would But in this particular case this can mask the underlying issues that have not yet been identified 7200 definitely supports both of these commands

I'm not sure if those commands are supported (and have no access to 7200 or ASR1k right now to verify), but try this: mpls ldp neighbor 200.200.200.200 targeted (use the loopback address of the peer, this works for individual peers) or mpls ldp session protection (this enables targeted hellos for all ldp neighbours - it has to be enabled on both peers) To see if it's working use show mpls ldp nei detail, you should see something like this: Peer LDP Ident: 10.16.16.16:0; Local LDP Ident 10.15.15.15:0 TCP connection: 10.16.16.16.11013 - 10.15.15.15.646 State: Oper; Msgs sent/rcvd: 53/51; Downstream; Last TIB rev sent 74 Up time: 00:11:32; UID: 1; Peer Id 0; LDP discovery sources: Targeted Hello 10.15.15.15 -> 10.16.16.16, active, passive; <----- this is the targeted session holdtime: infinite, hello interval: 10000 ms Addresses bound to peer LDP Ident: 10.0.0.2 10.16.16.16 10.101.101.101 11.0.0.1 Peer holdtime: 180000 ms; KA interval: 60000 ms; Peer state: estab Clients: Dir Adj Client LDP Session Protection enabled, state: Protecting duration: infinite the active,passive means that the router is both sending and accepting targeted hellos. kind regards Pshem _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
