Hi, Scenario is as follows: Data Center 1 - N7K-1, N7K-2. Data Center 2 - N7K-3, N7K-4. N7K-1 is the primary adjacency server N7K-3 is the secondary adjacency server Can't seem to find any sample config showing redundant OTV adjacency server configuration. Can anyone confirm if the attached config is correct in the Overlay interface ? Especially on N7K-3 (the secondary adjacency server) THanks Eng Wee

Your config looks like mine. This is how I have mine setup in my lab and it seems to work well. If its wrong then I'd like to know too
Overlay 1 is the overlay I use in my lab for this:

If in case you are trying to bring up OTV [unicast / mulitcast] using ASR1K, request you to kindly visit my blog: http://stayinginit.blogspot.in/2013/12/basic-unicast-overlay-transport.html
