ASR 1K+L2TP NOT WORKING FOR VLAN 1

Hi Team ,

 

We are trying to establish L2TP tunnel between two ASRs.

 

Topology is below :

 

ASR connected to ASR on other end which is connected to an unmanaged switch.

 

When configuring the tunnel between two sub interfaces , the tunnel is coming up . However we are not able to route traffic. We suspect the issue that unmanaged switch  on the other end is causing the issue as it can only forward traffic for 1 VLAN but we can't put sub interface in any vlan.

 

Can you suggest if we need to check anything other than changing the unmanaged switch ?

I would rule out the unmanaged switch first. If it works without then you know what device to tackle.
