VRRP

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> ipv4 vrrp state

Enables and disables VRRP for the interface. The default setting is disabled. For IPv6, run the nv set interface <interface-id> ipv6 vrrp state command.

In Cumulus Linux 5.14 and earlier:

The command is nv set interface <interface-id> ip vrrp.
You specify enable on or enable off instead of state enabled or state disabled.

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 swp1 ipv4 vrrp state enabled

nv set interface <interface-id> ipv4 vrrp virtual-router <virtual-router-id>

Configures the group of virtual gateways used with VRRP. For IPv6, run the nv set interface <interface-id> ipv6 vrrp virtual-router <virtual-router-id> command.

In Cumulus Linux 5.14 and earlier, the command is nv set interface <interface-id> ip vrrp virtual-router <virtual-router-id>.

Command Syntax

Syntax	Description
`<interface-id>`	The interface you want to configure.
`<virtual-router-id>`	The Virtual Router Syntax (VRID).

nv set interface <interface-id> ipv4 vrrp virtual-router <virtual-router-id> address <ip-address-id>

Configures a virtual address for VRRPv3. For IPv6, run the nv set interface <interface-id> ipv6 vrrp virtual-router <virtual-router-id> address <ip-address-id> command.

In Cumulus Linux 5.14 and earlier, the command is nv set interface <interface-id> ip vrrp virtual-router <virtual-router-id> address <ip-address-id>.

Command Syntax

Syntax	Description
`<interface-id>`	The interface you want to configure.
`<virtual-router-id>`	The Virtual Router Syntax (VRID).
`<ip-address-id>`	The IPv4 or IPv6 address.

Version History

Introduced in Cumulus Linux 5.0.0

Example

cumulus@switch:~$ nv set interface swp1 ipv4 vrrp virtual-router 44 address 10.0.0.1

nv set interface <interface-id> ipv4 vrrp virtual-router <virtual-router-id> advertisement-interval

Configures the interval between successive advertisements by the master in a virtual router group. You can specify a value between 10 and 40950 milliseconds. The default setting is 1000. For IPv6, run the nv set interface <interface-id> ipv6 vrrp virtual-router <virtual-router-id> advertisement-interval command.

In Cumulus Linux 5.14 and earlier, the command is nv set interface <interface-id> ip vrrp virtual-router <virtual-router-id> advertisement-interval.

Command Syntax

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

Example

cumulus@switch:~$ nv set interface swp1 ipv4 vrrp virtual-router 44 advertisement-interval 2000

nv set interface <interface-id> ipv4 vrrp virtual-router <virtual-router-id> preempt

Configures preempt mode, which lets the router take over as master for a virtual router group if it has a higher priority than the current master. The default setting is disabled. For IPv6, run the nv set interface <interface-id> ipv6 vrrp virtual-router <virtual-router-id> preempt command.

In Cumulus Linux 5.14 and earlier:

The command is nv set interface <interface-id> ipv vrrp virtual-router <virtual-router-id> preempt.
You specify enabled or disabled instead of on or off.

Command Syntax

Syntax	Description
`<interface-id>`	The interface you want to configure.
`<virtual-router-id>`	The Virtual Router Syntax (VRID).

Example

cumulus@switch:~$ nv set interface swp1 ipv4 vrrp virtual-router 44 preempt disabled

nv set interface <interface-id> ipv4 vrrp virtual-router <virtual-router-id> priority

Configures the priority level of the virtual router within the virtual router group, which determines the role that each virtual router plays and what happens if the master fails. Virtual routers have a priority between 1 and 254; the router with the highest priority becomes the master. The default setting is 100. For IPv6, run the nv set interface <interface-id> ipv6 vrrp virtual-router <virtual-router-id> priority command.

In Cumulus Linux 5.14 and earlier, the command is nv set interface <interface-id> ip vrrp virtual-router <virtual-router-id> priority.

Command Syntax

Syntax	Description
`<interface-id>`	The interface you want to configure.
`<virtual-router-id>`	The Virtual Router Syntax (VRID).

Version History

Example

cumulus@switch:~$ nv set interface swp1 ipv4 vrrp virtual-router 44 priority 254

nv set interface <interface-id> ipv4 vrrp virtual-router <virtual-router-id> version

Configures the VRRP protocol version for the interface. You can specify a value of 2 or 3. The default setting is 3. For IPv6, run the nv set interface <interface-id> ipv6 vrrp virtual-router <virtual-router-id> version command.

In Cumulus Linux 5.14 and earlier, the command is nv set interface <interface-id> ip vrrp virtual-router <virtual-router-id> version.
