Which command is critical in order for OTV edge devices to maintain an overlay adjacency with their local
peers in a multihomed site via the join interfaces across the Layer 3 network domain?
A.
otv site-identifier
B.
otv extend-vlan
C.
otv site-vlan
D.
otv use-adjacency-server unicast-only
Step 3 otv site-identifier id
Example:
switch(config)# otv site-identifier 256
Configures the site identifier. You should configure this same site identifier on all local OTV edge devices. The site identifier should be unique across different sites. The range is from 0x0 to 0xffffffff. The default is 0x0. The format is either hexadecimal or MAC address format.
Note
This configuration step is required for Cisco NX-OS release 5.2(1) and later.
