                   Hi,

One of our ldp neighbour in the router not showing recv in targeted hello in one end

ospf neighbour is up, ldp neighbour is up

sh mpls ldp discovery

Local LDP Identifier:

    172.16.26.28:0

    Discovery Sources:

    Interfaces:

GigabitEthernet2/18.1512 (ldp): xmit/recv

            LDP Id: 172.16.26.74:0

sh mpls ldp discovery

    172.16.26.28:0
    Discovery Sources:
    Interfaces:

            LDP Id: 172.16.26.74:0

Targeted Hellos:

172.16.26.28 -> 172.16.26.74 (ldp): active, xmit

no password config is present

mpls ldp router-id Loopback force command is present

no access list configured on this neighbour

mpls ip & global ldp is configured on that interface

both the router having multiple other link & all that link having no issue except the above

both side is pingable

only problemativ side no showing "recv" , but remote end showing "xmit/recv"

Pls suggest further

Hi Subhojit,

What is the targeted ldp session used for; Eompls, LDP over MPLS TE, LDP session protection? It looks like one side is configured for this feature and the other one not.

Hi,

We are using Ethernet over mpls & also TE config is there

Pls suggest possible reason for not showing this

[Harold Ritter]

Hi Subhojit,

Do you run LDP over the MPLS TE tunnel? If the targeted LDP is used for EoMPLS, can you please check whether the pseudowire is up?

Regards

Hi,

Sorry for earlier post

we are using this for ldp session protection & found that remite end router LDP session protection config is not present

we will do the config at remote end & let u know

Thanks gor guiding
