Configure the VLT interconnect between Leaf1 and Leaf2. In this configuration, add interfaces hundredGigE
1/31 – 1/32 to static port channel 127 for the VLT interconnect. The backup destination is the management IP
address of the VLT peer switch.

Interface Te 1/33 connects downstream to Server 1 and is configured as an RSTP edge port. Interfaces Fo
1/1/1 and Fo 1/3/1 connect to the spines upstream and are configured in LACP port channel 1. The port
channel is configured for VLT.
