ASR OTV with access port

[Debabrata Majhi]

Hi All

I want to Extend only one vlan to other Data center for some migration purpose.The following configuration is example for trunk port to carry multiple vlan.But my need only one vlan.

Can we configure the L2 connectivity with OTV router and L2 switch access port instead of trunk port?

If I configure the switch access port what will be configuration in OTV overlay interface,As we can see it is  

encapsulation dot1q 100(Vlan)

Is it possible to configure OTV with access port? 

service instance 50 ethernet
  encapsulation dot1q 100
  bridge-domain 200

ASR-1
 interface GigabitEthernet0/0/2
  no ip address
  negotiation auto
  cdp enable
  service instance 1 ethernet
   encapsulation untagged
   bridge-domain 1

  service instance 50 ethernet

Hi @Debabrata Majhi,

You should configure the L2 connectivity between the OTV Router and L2 switch as Trunk port.

Untagged Ethernet frames are not forwarded by the OTV Router.

Hope this helps.
