L2TPv3 tunnel between Cisco IOS and ASR 9000 IOS-XR

Hi All,

I am trying to establish L2TPv3 VLAN-to-VLAN based pseudowire between Cisco NPE-G2 and ASR 9001 routers but could not bring the pseudowire up and end to end reachability.

Below are the configuration:

ASR:

RP/0/RSP0/CPU0:LAB-ASR1#sh run l2vpn

Tue Sep 10 22:50:02.204 UTC

l2vpn

pw-class test

  encapsulation l2tpv3

   protocol l2tpv3 class test

   ipv4 source 10.10.10.103

   transport-mode vlan

  !

!

xconnect group l2tpv3

  p2p lab1-2

   interface GigabitEthernet0/0/0/1.101

   neighbor 10.20.0.3 pw-id 100

    pw-class test

   !

RP/0/RSP0/CPU0:LAB-ASR1#sh run l2tp

Tue Sep 10 22:50:10.190 UTC

l2tp-class test

authentication

password 7 095F470F00544541

!

RP/0/RSP0/CPU0:LAB-ASR1#sh run int gi 0/0/0/1.101

Tue Sep 10 22:50:18.071 UTC

interface GigabitEthernet0/0/0/1.101 l2transport

encapsulation dot1q 101

!

NPE-G2:

l2tp-class test

authentication

password 7 071C284A57584B56

!

pseudowire-class test

encapsulation l2tpv3

protocol l2tpv3 test

ip local interface Loopback0

CE1-NPEG2#sh run int gi 0/3.101

Building configuration...

Current configuration : 106 bytes

!

interface GigabitEthernet0/3.101

encapsulation dot1Q 101

xconnect 10.10.10.103 100 pw-class test

end

CE1-NPEG2#

Have anyone tried L2TPv3 between IOS and ASR 9001 and working?

thanks in advance

Arun

Hi Arun/Nuno,As I just got

Hi Arun/Nuno,

As I just got update from Cisco ASR 9000 doesn't support l2tpv3 over IPv4 please try it over IPv6.
