Dear all,

I am seeing LDP session established for none directly connected peers.

I can understand this being the case when using targeted LDP for previously connected peers which have lost L1 link for example...but cannot see why remote peers with no explicit LDP peering are establishing sessions.

here is a sample of my config:

mpls label protocol ldp

tag-switching tdp router-id Loopback10 force


mpls ldp neighbor pass sam

mpls ldp neighbor pass sam

mpls ldp explicit-null

no tag-switching advertise-tags

tag-switching advertise-tags for SAM

tag-switching tdp discovery


directed-hello accept from SAM

ip access-list standard SAM


and under interfaces :

mpls label protocol ldp

Any thoughts as in why am LDP sessions are just being established ?

It could be that you are running LDP on a MPLS TE tunnel as follow:

interface tunnelxx

mpls ip

Thanks for the reply Harold,

I am not using TE, just plan LDP sessions.
