[f-nsp] LDP issues with Foundry/Juniper

[Dan Spataro]

Hi,

I am having an issue getting a Foundry XMR to establish LDP with a
Juniper M40.  The Juniper already has many LDP sessions established with
many other Junipers.  When I debug the Foundry it says the TCP
connection is not getting established with the Juniper.  I initially
thought it could be an issue with the Junipers Routing Engine filter
blocking the LDP traffic. I dropped the filter and LDP still will not
come up

This is what I get when I debug mpls ldp socket on the Foundry XMR

Oct 19 15:11:51 LDP: Start connecting 209.123.12.85 local_port 9131 (tcb

When I show ldp session detail on the Foundry XMR is says this

Peer LDP ID: 209.123.12.85:0, Local LDP ID: 209.123.12.121:0, State:
Nonexistent
  Adj: Link, Role: Active, Next retry: 93 sec
  Keepalive interval: 6 sec, Max hold time: 36 sec
  Neighboring interfaces: e1/1, (targeted)
  No TCP connection available

Any help will be greatly appreciated.

Thanks
Dan
