VPLS Not Working on Cisco IOS XR CRS 5.3

[bzsupergirl1]

Hi Everyone,

I am simulating VPLS (Multipoint l2vpn) on Cisco IOS XR CRS devices on GNS3. I have setup a PW between LER1_xr1 and LER2_xr2 by defining a bridge-domain and a vfi. The PW is up but I can't ping from Ubuntu1 to Ubuntu2.  Following talks more details.

Thanks so much!

Do you have an MPLS forwarding entry in your PE devices for the remote device you are sending traffic to?

[bzsupergirl1]

Yes. I think it has.

On LER1_xr1：

RP/0/0/CPU0:LER1_xr1#show mpls forwarding

If there is an mpls label for the other side than LDP is working and advertising networks correctly.  Can you ping the remote host via the mpls pseudowire ID of 100? I think it's something like

ping mpls pseudowire 2.2.2.2 100 

If you can ping the devices on either side of the l2vpn than it may be something between your PE and the hosts.

[bzsupergirl1]

Yes, it could ping through and the problem should lies in the PE and the hosts. Some one just replied me that VPLS could not be simulted by GNS3.

Thanks so much for your kind help :)

I dont think it will work on GNS3

The question is already answered in another post. VPLS is not supported on GNS or XRv as it is a platform dependent feature and requires physical hardware. Only control-plane will function.
