How to configure VPLS L2VPN Pseudo Wire with MPLS

How to configure VPLS L2VPN Pseudo Wire with MPLS

Hello, I'm needing some help setting up a layer 2 vpn between two X460-24t across a wan. I have all the necessary licensing and feature packs installed. The wan used static routing and is 3 hops away, also the routers in between do not participate in the MPLS. I've started setting up the MPLS and VPLS here's where I'm at...What am I doing wrong?

Hmm not a MPLS expert but when we need to pass MPLS framing at layer 2 across a non-mpls switch then we build a vman and enable jumbo frames on the per layer 2 switches to tunnel the mpls traffic through. On the 450's there are some restrictions if you want to pass standard tagged vlans and vmans on common trunk ports. Not sure if this will help or confuse

Thanks, one limitation is that I can not enable jumbo packets the the wan link does not support jumbo packets.

Hi Prashanth, yes there is routers in between there are X450a with only Advanced Edge licening so I can't enable MPLS. I would think that the X450a would pass the MPLS traffic? Is there something that would stop them from doing so?

Thanks again, Matt

Prashanth, I wonted to add that was checking the advertising of each of the routers. I'm seeing a diffrence on the two routes.

snj-xm0-nsw010.8 # sh mpls ldp label advertised

Advertised Destination Label Peer NHop
Label Mapping Flags Label Type NextHop Name
-------------------------------------------------------------------------------
0x00434 192.168.122.1/32 -LE -- vlan lpbk --
0x00435 192.168.155.1/32 2LE -- VPLS -- vpls-snj-bkd022

(M) Multiple Next Hops

ldc-xm0-nsw012.9 # sh mpls ldp label advertised

-------------------------------------------------------------------------------
0x00434 192.168.122.1/32 2LE -- VPLS -- vpls-ldc-bkd55

Is this some ting to look into?

Thanks Matt
