ASR1001 OTV Vlan 1

Can you span VLAN 1 over OTV? I have other VLANs working, just not VLAN 1

Re: ASR1001 OTV Vlan 1

You should be able to do  :

 

https://www.cisco.com/c/en/us/support/docs/routers/asr-1000-series-aggregation-services-routers/117158-configure-otv-00.html

 

need to provide more information and configuration. 

 

Note: Do NOT extend the site VLAN on the overlay interface. This causes the two ASRs to have a conflict because they believe that each remote side is in the same site.

Re: ASR1001 OTV Vlan 1

Hi, Mackim, 

Try rewriting tags in service instance 1 adding corresponding tags for native VLAN: adding tag on ingress and removing it on egress. The other solution might be tagging native VLAN on trunk. Also, as previously noted, make sure not to advertise site VLAN via OTV.
