Configure VXLAN BGP EVPN and OTV Interoperation on the Border Leaf Switches in DC-1 and DC-2
Step 2 Configure the VXLAN overlay loopback interface
BL1(config)# interface loopback0
• Primary and secondary IP addresses are assigned to the source loopback interface on the switch.
Step 3 Configure tunnel switching in the OTV overlay
BL1(config)# feature otv
• The otv site-vni command enables the OTV site specific VNI. This VNI should not be extended over
any overlay interface and should be operationally up before it can be configured as the OTV site VNI.
At least one interface should be present where the VNI is up. On a VXLAN + OTV pod, the VNI can
be configured under the NVE interface. If the otv site-vlan configuration is enabled, then you need to
remove it before configuring the otv site-vni command.
• The otv tunnel-stitch command is the OTV command for connecting VXLAN and OTV tunnels.
• For OTV overlays, only Generic Routing Encapsulation (GRE) encapsulation is supported for the 8.2(1)
release.
You should enable ARP proxy under the OTV overlay and ARP suppression under the VXLAN overlay
Note
at the same time or you should disable both the functions.
Step 4 Configure the VXLAN and OTV tunnel stitching configurations on BL2.
Step 5 Configure vPC function on BL1 and BL2
vPC Peer 1 (BL1) configuration
BL1(config)# interface Bdi3500
vPC Peer 2 (BL2) configuration
BL2(config)# interface Bdi3500
