This document provides the configuration example for deploying OTV in the Data Centers having multiple VRFs.
There are two Aggregation VDCs in each data center having three VRFs Web, App and DB. Both the Data Centers are connected via two 10 Gig circuits connected directly to the Aggregation Layer switches.
Main purpose of this document is to show OTV related configuration both at the OTV VDC and at the Aggregation VDCs.
There are three vlans 701, 750 and 775 are extended between the two Data Centers through OTV. These VLANs have SVIs at the aggregation layer corresponds to the three different VRFs.
OTV join interface in the OTV VDC is configured in the default VRF.
OTV join interface in the Aggregation VDC is configured in the App VRF. The choice of VRF is depends on the customer network.
The Layer 3 VRFs are extended between the two Data Centers and OSPF is the IGP protocol.
OTV Adjacency Server Unicast is used in this configuration example.
