Hello All,
I'm trying to configure a L2TP tunnel between two ASR9Ks. The configuration is pretty straightforward and the tunnel came up tidy. However I’m unable to pass traffic throught the tunnel. All the traffic if dropped in the inbound interface.
Configuration
interface GigabitEthernet0/0/0/5.100 l2transport
encapsulation dot1q 100
!
l2vpn
pw-class L2TP-CLASS
encapsulation l2tpv3
protocol l2tpv3 class L2TP-CLASS
ipv4 source 172.25.200.10
transport-mode vlan
!
xconnect group L2TP
p2p L2TP
interface GigabitEthernet0/0/0/5.100
neighbor 172.25.200.11 pw-id 654
