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
