Could you please provide the output for "show mpls ldp discovery" and "show mpls ldp nei" from the cisco side.

Hi harold,

Please find the requested o/p's

sh mpls ldp discovery

Local LDP Identifier:

    1.1.1.1:0

    Discovery Sources:

    Interfaces:

GigabitEthernet0/1.1510 (ldp): xmit/recv

    LDP Id: 2.2.2.2:0

GigabitEthernet0/1.1511 (ldp): xmit/recv

    LDP Id: 2.2.2.2:0

    Targeted Hellos:

1.1.1.1 -> 2.2.2.2 (ldp): active, xmit

sh mpls ldp neighbor

    Peer LDP Ident: 2.2.2.2:0; Local LDP Ident 1.1.1.1:0

TCP connection: 2.2.2.2.54811 - 1.1.1.1.646

Do you have an access-list on either side of the session? Would it be possible to provide the configuration from both sides?

Thanks Harold,

But the issue was resolved from Juniper end. They need to explicitly add loopback0 interface for mpls ldp to advertise label for Loopback IP.

Once they did it the xconnect came UP.

I'm glad you found the solution.
