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 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.

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface vlan10 ip vrr address 10.1.10.1/24 

nv set interface <interface-id> ip vrr enable

Turns VRR on or off on the interface. The default setting is off.

Virtual Router Redundancy (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.

Command Syntax

Syntax Description
<interface-id> The interface you want to configure.

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface vlan10 ip vrr enable on 

nv set interface <interface-id> ip vrr mac-address <mac-address>

Configures anycast MAC override on the interface.

Command Syntax

Syntax Description
<interface-id> The interface you want to configure.
<mac-address> The anycast MAC address.

Version History

Example

cumulus@switch:~$ nv set interface vlan10 ip vrr mac-address 00:00:5E:00:01:00

nv set interface <interface-id> ip vrr mac-id <fabric-id>

Configures the fabric ID override on the interface.

Command Syntax

Syntax Description
<interface-id> The interface you want to configure.
<fabric-id> The fabric ID.
