Routing

Hi All

I've one special condition as follow :

Switch B connect to router B with two vlan into one l2circuit vc. And switch A connect to router A with one vlan

As follow is diagram :

I tried to test and seems it's not working. L2circuit connection is up ,but Ping failed.

Is it possbile to reach it ?

As attachment is my configuration 

Thanks

Hi Cloud,

I don't see any vlan config on the interface on router A.

Hi 

Yes, as you saw I don't set any vlan config on router A.

Because switch A connecting to router A by using the access mode without tag vlan id.

 I hope side A without vlan can connect to any vlan on side B.

Therefore, I need to strp off vlan id on side B.

Is it possbile to reach this target ?

Best regards,

Not with plain L2circuits. Plain Type-4 L2circuits are point-to-point only, meaning the number of VLANs is 1 on each side.

You will need VPLS (BGP VPLS., or if You don't need/want/can't afford BGP VPLS).

If LDP VPLS, then the L2circuit config can stay on one side (let's say side A for certainty) and the following config would be needed only on the other side (i.e. side B for certainty):

routing-instances {
    LDP-VPLS {
        instance-type vpls;
        vlan-id none;
        interface xe-1/2/0.123; ## local IFL with tag 123
	interface xe-2/3/0.456; ## local IFL with tag 456
        no-local-switching;
        protocols {
            vpls {
                no-tunnel-services;
                vpls-id 1024; ## the virtual-circuit-id on the side A must be also 1024
                neighbor 203.0.113.41 { 
                    encapsulation-type ethernet;
                }
            }
        }
    }
}

Hi 

I think LDP-VPLS is what I would like when L2circuit is only support P2P. 

Thanks for your sharing
