Hi,
I have a network setup with one Nexus 7000 at the Primary and the other at the DR.
I have setup otv over a layer 3 point-to-point link between the two sites. Recently a second point-to-point link was provisioned be a different service provider.
How do I setup the OTV so that I can utilize both links to have one link as the active and the second as standby with failover.
Thanks.

Is your join interface the point-to-point link? Please provide more information...

I have two point to point links between the two Sites, I would like to use both interfaces at each site as join interfaces so that the DCI can failover to the second link in case the first p2p link is down.

Form a port-channel. Link with lowest priority wins and will always be active when available. You must specify that only 1 link in the bundle can be used. I haven't tried this config on N7K's so syntax might be a bit different, but this is generally how it would be achieved.
interface Po1
lacp fast-switchover
lacp max-bundle 1
!
interface Ex/x
description PRIMARY
channel-group 1 mode active
lacp port-priority 10
!
interface Ex/x
description SECONDARY
channel-group 1 mode active
lacp port-priority 100

Thanks,
I am still facing a challenge as the LACP is not working across the Layer 3 Service Provider links

can you explain a bit more please? what do you see when you do a show port-channel summary?
