We have OTV Between 2 Data Centers , it is works fine . 

We need to creat another OTV Between the same 2 Data Centers . 

The question is how to prefer one OTV To another ? 

 

Thank you,

OTV also builds adjacencies with other edge devices in the local site. OTV sends OTV control-plane hello messages on a dedicated VLAN, which is the site VLAN, to detect other edge devices in the same local site. These edge devices communicate to elect the Authoritative Edge Device (AED) for each configured overlay network.

 

If you have two AEDs, the vlans are split into odd and even for loadbalancing between the AEDs. This is automatic and no additional config is needed.

 

You can refer to the guide for configuration details -
