MPLS over L2TP

Hi,

Has anyone connected two PE routers over L2TP tunnel? I have a case where I have to go through a third party L3 network. I would like to exchange LDP over the tunnel. Can someone point to a good doc on the web or provide a sample config.


thanks

Arana

Hritter,

Is the configuration for CE-PE? I was talking for PE-PE. I need to exchange LDP with the PE routers just like a leased line, only that there is an IP netwokr in between.


Thanks,

Arana

Arana,


The solution I provided is indeed for the PE-PE interconnection and is ususally used when you don't already have an MPLS core but that you want to deliver l3vpn services.


If you already have an MPLS core but that you want your traffic to traverse a network that is not MPLS enabled, you could just do MPLS over a GRE tunnel:


int tu0

ip address x.x.x.x y.y.y.y

tunn source s.s.s.s

tunn destination d.d.d.d

mpls ip
