Routing

Hi All !

I need your help since I didn't manage to acheive what I wanted.

1) I have PE-SPOKE which is connected inside a VPLS instance  to many other PE via Martini L2VPN. All the traffic is then forwarded to the HUB PE-HUB inside this VPLS instance

instance-type vpls;
protocols {
    vpls {
        vpls-id 1024;
        ignore-mtu-mismatch;
        neighbor PE-HUB;
        mesh-group SPOKE {
            neighbor N1 {
                vpls-id-list [ N1-PW1 N1-PW2];
            }
            neighbor N2 {
                vpls-id-list [ N2-PW1 N2-PW2 N2-PW3];
            }

        }
    }
}

2) the traffic has to be delivred to the PE-HUB which is connected to the customer PE on a tagged interface.

3) The probleme is that the traffic that comes from each PW (from N1-PW1 to N-PW3) can be eighter tagged or untag (802.1Q).

here is what i did about the "vlan-id" statement inside the VPLS routing-instance

OK : means end-to-end ping successful

I also tried to play with the vlan-map but  I didn't manage to get what I wanted !

Thanks for your help...

Hello,

Please post the printout "show vpls connections extensive | no-more" for cases "none|none" and "all|all".

I suspect You are using Type-4 PW which by default pass only tagged frames.

I would suggest to nail down the PW type to Type-5 ("encapsulation-type ethernet") which passes both tagged and untagged frames.

Thanks

Hi Alex !

Thanks a lot for your help.

All the PW where type 6 ("encapsulation-type ethernet"). I think that my concept was wrong with only a tagged without native vlan) interface on the PE-Customer...

Hummm after some reflexion,

it's seems that what I asked is not possible in term of concept : how we can know when we have to remove the tag for the traffic from the Custumer PE ? Not possible.

Solution : use a dedicated interface for this instance with encapsulation ethernet-vpls
