Any idea ? Does informations incomplete ?

Is it so hard problem ? anybody heard something about VPLS ?

Mplsguy · June 2, 2010, 1:16pm

From your config I understand that your VPLS endpoints are not on the same subnet (are not directly connected). In order for such a tunnel to work you need MPLS LSP between both endpoints that would transport VPLS packets. There clearly is no such LSP in your setup, because the only LDP neighbour you have is remote VPLS peer. So as minimum you must enable LDP on all routers between VPLS endpoints.

I suggest you carefully study MPLS/VPLS related docs here:
http://wiki.mikrotik.com/wiki/MPLS

Hello Mplsguy

Just want to ask similar question related with this configuration reported above, In my understanding is possible to transport VPLS using BGP and L2vpn to transport the VPLS information and create dynamic VPLS tunnels, in the above scenario where network is not continuos and crossing multiple IP backbone routers Non-MPLS could be possible to set such VPLS and have it running state? I tried such configuration, have VPLS Tunnels stablished dynamically created and BGP signaled but not running state as well; there is anyway to make this works over the IP backbone? I know this RFC4364 mentioned the possibility and I know Mikrotik support it.

I followed below instructions where LDP is no needed because BGP L2VPN family does the transport:
http://wiki.mikrotik.com/wiki/BGP_based_VPLS

Thank you!
