ASR 9901 vpls configurations issue

[Mostafa Alzareef]

I have 8 PE routers (ASR 9901 running IOS XR) and need to test reachability using VPLS. Specifically, I want to connect a laptop to an interface on PE-1 and another laptop to an interface on PE-2, then perform a ping test to verify connectivity between the routers.

I'm facing an issue with configuring l2transport on the interface, as the following commands aren't being accepted:

interface GigabitEthernet0/0/0/0
l2transport s
ervice-instance 1 # Not accepted################################
encapsulation untagged  # Not accepted################################
rewrite ingress tag pop 1 symmetric # Not accepted################################

Here's the full configuration I've applied so far:

l2vpn
bridge group VPLS-Group
bridge-domain VPLS-Domain
vfi VPLS-VFI
neighbor 192.x.xx.xx pw-id 100
exit
exit
exit
exit
interface TenGigE0/0/0/12
l2transport
mtu 9216
exit
interface GigabitEthernet0/0/0/0
l2transport
service-instance 1
encapsulation untagged
rewrite ingress tag pop 1 symmetric
exit
exit

Here is an example of VPLS configuration
- use l2transport subinterface instead of physical interface
- service-instance is not used in IOS XR
- for untagged encapsulation rewrite is not necessary 

!
interface GigabitEthernet0/0/0/0
!
interface GigabitEthernet0/0/0/0.10 l2transport
encapsulation untagged 
!
l2vpn
bridge group VPLS-Group
 bridge-domain VPLS-Domain
  interface GigabitEthernet0/0/0/0.10 l2transport
  !
  vfi VPLS-VFI
   neighbor 192.x.xx.xx pw-id 100
!

Many thanks for your support your configurations is working fine
