Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

For IPv4, you can configure a VRRP group to use one of the following VRRP versions:

• VRRPv2 as defined in RFC 3768, Virtual Router Redundancy Protocol (VRRP) 

• VRRPv3 as defined in RFC 5798, Virtual Router Redundancy Protocol (VRRP) Version 3 for IPv4 and IPv6

You can also migrate a IPv4 group from VRRPv2 to VRRP3.

To configure the VRRP version for IPv4, use the version command in INTERFACE mode.

Example: Configuring VRRP to Use Version 3

The following example configures the IPv4 VRRP 100 group to use VRRP protocol version 3.

You can use the version both command in INTERFACE mode to migrate from VRRPv2 to VRRPv3. When you set the VRRP version to both, the switch sends only VRRPv3 advertisements but can receive VRRPv2 or VRRPv3 packets.

To migrate an IPv4 VRRP group from VRRPv2 to VRRPv3:

1. Set the switches with the lowest priority to “both”.

2. Set the switch with the highest priority to version to 3.

3. Set all the switches from both to version 3.

Example: Migrating an IPv4 VRRP Group from VRRPv2 to VRRPv3

To migrate an IPv4 VRRP Group from VRRPv2 to VRRPv3:

1. Set the backup switches to VRRP version to both.

2. Set the master switch to VRRP protocol version 3.

3. Set the backup switches to version 3.
