For OTV extended VLAN, how to make traffic from WAN be routed correctly?

[gwhuang5398]

I'm OTV a VM VLAN across two data centers. The VLAN also has identical HSRP configured on the Aggregation VDC at each data center site. So both data centers are advertising this VM subnet out to the WAN. When a remote site tries to reach the VM subnet from the WAN, how can I make sure it's routed to the correct data center where VM is active?

Thanks

Hello,

This is a trick part. Several methods exist to control and manage inbound routing, including Route Health Injection (RHI), Null Aggregation and Locator Indentity Separation Protocol (LISP).

Each these, there are one better use depending of scenario. I could start to explain but this is a very broad subject.

Keep in mind that also can be done with a Global Load Balancer solution.
