This example uses 100 GbE interfaces 1/1/29 and 1/1/30 for the VLTi between the two external switches. Use the no switchport command to remove each interface from the Layer 2 mode. Use the mtu 9216 command to enable jumbo frames on the VLANs.
Create the VLT domain. The backup destination is the OOB management IP address of the VLT peer switch. Configure the interfaces used as the VLTi with the discovery-interface command. Specify a virtual MAC address that the switches will share. Enable peer routing.
Note: The manual configuration of the VLT MAC address minimizes the time required to synchronize the default MAC address of the VLT domain on both peer devices when one peer switch reboots.
