MPLS via GRE tunnel issue

Dear all,

I want to deploy MPLS in IP tunnel environment so  i tried to create on a pair of ASR 920 a GRE tunnel via IP environment for testing, enable ospf and ldp on the tunnel. Everything seems fine but when I establish a l2vpn service (xconnect), i realized that I can’t pass traffic via the pseudo-wire although VC is up and ping mpls successful. Anyone can support me? Thank so much :)

Hi,

 

Are you able try configuring below command under service instance and test if resolve your problem?

 

- rewrite ingress tag pop 1 symmetric

 

Regards

Hi dialondemand
I configured untag mode under service instance as bellow so i think "rewrite..." is not necessary

interface GigabitEthernet0/0/18
no ip address
no negotiation auto
no keepalive
service instance 100 ethernet
encapsulation untagged
xconnect 3.3.3.3 100 encapsulation mpls
!
end

Hello,

 

GRE may not be supported in the dataplane of ASR920. Which IOS XE version do you run on both routers?

 

Best Regards,

 

Peter
