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 ?
In the last year, we’ve seen substantial changes in how enterprises conduct business. When the pandemic hit, it exposed gaps in business continuity plans, and it showcased the need to quickly deploy and remotely manage secure connections.
