Hello,
We are moving data centers. We have metro ether circuit between two data center and we are using ASR routers (CE) at both locations. The ports on the ASRs connected to metro ethernet are layer 3 using 172.16.1.0/24 address range to connect the two data centers. We would like to extend layer 2 to prevent re-addressing hosts that will be moved to the new data center.
How can this be accomplished? There's a lot of information online regarding layer 2 extension such L2TPV3, OTV, etc but I'm just not sure which one to use. Any advise and sample configurations would be appreciated. Thank you!
Richard
