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 172.16.0.5 pass sam

mpls ldp neighbor 172.16.0.6 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


permit 172.16.0.0 0.0.0.255



and under interfaces :

mpls label protocol ldp



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


TIA


Sam

Sam,


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.
