LDP Based VPLS tunnel

RouterOS Forwarding Protocols
1

Hi

We are trying to establish an VPLS tunell over an established network. The networks are connected thru external IPSEC and we have basic ip-routing in place.

We have previously been using EOIP, but would now like to connect multiple sites using the same subnet and hence we are looking into VPLS.

We have LDP session running and setup VPLS, but VPLS tunnels are not seeing any traffic, for testing we have tried to ping from router-a-vpls1 to router-b-vpls2, isnt this supposed to work, just like it does on EOIP ?

This stuff usually boils down to MTU most of the time.MPLS/VPLS is a whole lot more complicated than EOIP , so you’re gonna have to read up quite a bit how it works.Have a look at the Wiki as well as documentation written by Greg Sowell,Andrew Thrift and Tomaskir.

Can you see MPLS labels being exchanged through Winbox ? Are you using a routing protocol to exchange routes or are you using static routing ? Are you able to ping the MPLS loopback/transport addresses ?

Hi

We are using static routing and transports are pingable. Both end-points show route labels from each other, so I cannot see anything wrong here.

The vpls interfaces is totalyb dead, no data is transferred.

No mpls over layer 3.

Look into eoip or l2tp.

Edit : you can do vpls over mpls over l2tp over ipsec if you want to :smiley: .

Could you post your config ? It sounds like you’re on the right track.I’m still betting on too small of a MTU.
