BGP and MPLS

Sat Nov 15, 2014 1:22 pm

Hello.
My question is: is it possibile to setup MPLS/VPLS between my mikrotik routers having BGP as dynamic routing protocol instead of OSPF?

Thanks

To clarify the question: Is it possible to redistribute LDP with BGP and avoid OSPF ?

Regards,

Thanos

Yes. All that's needed is a routed infrastructure - the protocol used is irrelevant.

Nope.
LDP explicitely do not use bgp routes to distribute lables.
All routes excepg the bgp could be used, i.e. ospf.

Interesting, I suggest you test it.

I agree with Barkas. However, the wiki ( http://wiki.mikrotik.com/wiki/Manual:MPLSVPLS ) clearly states that LDP by default distributes labels for active IGP routes (that is - connected, static, and routing protocol learned routes, except BGP).

I added the loopback address (/32) to the bgp networks and the vpls tunnels established successfully, routeros >= 6.19

Topology (all routerOS):
A -- B -- C

A -- B: eBGP
B -- C: eBGP
A -- C: VPLS tunnel

Thanos

I did think a colleague of mine had it running this way.

I tried your configuration but vpls does not esthablish, routes dinstributed by bgp are not used by ldp in my case
