Can OTV run over an existing layer 2 link?


I have two sites connected via a layer 2 handoff from the ISP.  The L2 link terminates into an ASR.
Do I need to convert it to layer 3 to be able to do OTV?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

OTV (Overlay Transport Virtualization) is used to extend Layer 2 applications without the need to convert to layer 3.

Akinsd is right.

The link between sites is L3 already anyway as you have a link between the ASRs, so from the side you want to extend it's routed anyway.
As long as layer 3 connectivity exists between locations OTV allows you to basically tunnel layer 2 inside layer3.
OTV is MAC-in-IP.

Here is a good link for configuring OTV on an ASR -
