VRR
The nv unset commands remove the configuration you set with the equivalent nv set commands. This guide only describes an nv unset command if it differs from the nv set command.
nv set interface <interface-id> ip vrr
Configures Virtual Router Redundancy (VRR) for an interface. VRR enables hosts to communicate with any redundant switch without reconfiguration by running dynamic router protocols or router redundancy protocols. Redundant switches respond to ARP requests from hosts. The switches respond in an identical manner, but if one fails, the other redundant switches continue to respond. You use VRR with MLAG.
nv set interface <interface-id> ip vrr address <ip-prefix-id>
Configures the VRR virtual address and prefix.
Command Syntax
| Syntax | Description |
|---|---|
<interface-id> | The interface you want to configure. |
<ip-prefix-id> | The IPv4 or IPv6 address and route prefix in CIDR notation. |
