Who has done it?

I need a "pseudowire" over VPLS. I can't get it work. Tagged packets are not going through the VPLS.

hm... maybe 'Use Service Tag' checkbox in VLAN Properties is for you?..

use-service-tag simply changes protocol that is used for VLAN encap. In case you want to bridge VLAN tagged packets you do not need any VLAN interface at all. Most likely cause of VLAN encapsulated packets to not get bridged is l2mtu issues - e.g. VPLS interface l2mtu is only 1500 (so it can take "full size" regular ethernet packet, but not full size packet with VLAN tag). l2mtu value for VPLS interfaces is taken from advertised-mtu parameter.

hmmm... what about fragmentation?..

No guys,

in the lab everything is working perfect. Something in teh production envirnonment must be wrong.

@mplsguy: l2MTU of the vpls interface should only affect when full frames are sent but not with pings. In that case the packet will never reach the mtu size limit.

hmmm... what about fragmentation?..

What about it? RouterOS VPLS pseudowires support frame fragmentation/reassembly according RFC 4623. This means, that if l2mtu of VPLS will exceed outgoing link MPLS MTU plus any space needed for VPLS+MPLS encapsulation, frame will get fragmented.

Ok, then I guess you simply have to find out in what way your lab setup differs from production environment. In case you have trouble sorting the issue out, please describe your setup and post relevant parts of configuration.

hi to all

I have a complete Mikrotik Infrastructure and I have implemented VPLS between my Base station and my pppoe server

How can I intergrate VLAN in this architecture


regards

You need to ensure your PPPoE server (BRAS) is able to accept dot1q VLAN tags. Then you can use VPLS to extend the VLAN over a routed MPLS network all the way to the end subscriber at the edge.

You must have a minimum L2 and MPLS mtu of 1530 to hand off a tagged 1500 byte frame
