VPLS TE multiple loopback

RouterOS Forwarding Protocols
1

Hi,

have this problem.
I have a network with aroung 10 router.
Evaluate router A and router Z.
Beetwen this router I have setup Loopack and I have create TE tunnel for manage traffic.
Now I want on the same router create anoter TE tunnel and attached vpls interface that fllow another path.
For make this I have create another loopback interface on both router and establish beetwen this 2 new ip address.
The problem is that second TE tunnel work but VPLS interface remain down.

Some conf:
0 R name=“EtoI” mtu=1500 disable-running-check=no from-address=auto to-address=10.10.10.9
bandwidth=5Mbps primary-path=force-router secondary-paths=dyn primary-retry-interval=10s
record-route=yes reoptimize-interval=10s bandwidth-limit=disabled auto-bandwidth-range=0bps

hmmm. it sounds a bit off in config. Do you have full MPLS support between devices? ospf? Then you should just have 1 loopback at each device, a link net - and MPLS enabled and connect VPLS to the loopback ip. Not make one more loopback etc..

yes,

ldp enabled on al interface and router of network.

If I establish vpls beetwen first loopback, work corretly. (first ip loopback is also the address specified into ldp transport address).

My question is at this point: is possible establish multiple tunnel but with different path on same router?

Thanks

This i have never tried - but its possible -but i dont think a 2 loopback is the clue… maybe if you have static routes, but in a ospf enviroment - i dont think its possible to have 2 ways 2 core at the same time. but maybe with a small “hack”. You need to use ospf cost in order to know where the traffic will “go” and Connect to the farest possible “away” the “2 path” to VPLS peer, and terminate here. Then another VPLS from this and to core -and brige em.

It should also be possible to have some kind of manual route to core.

We lack the possibility to have 2 services at the same router in different vrf’s. This would be “the way” - but today its not possible. its a requested feature.


Btw - What is the final goal ? some kind of bonding 2 VPLS trough different path to have more speed? - The “backup” feature you would already have, by ospf changing the path for LDP to VPLS peer if something goes down. So the l2 interface will be “online”. If you need more than 1 " line" etc, you can/should use vlan inside the VPLS tunnel, or if its 2 subnet’s withn ip - and you dont need the l2 feature - setup bgp with confederation at all routers, and use vrf inside the MPLS paths.
