Conguring the VRRP Version for an IPv4 Group
For IPv4, you can congure a VRRP group to use one of the following VRRP versions:
• VRRPv2 as dened in RFC 3768, Virtual Router Redundancy Protocol (VRRP)
• VRRPv3 as dened 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 congure the VRRP version for IPv4, use the version command in INTERFACE mode.
Example: Conguring VRRP to Use Version 3
The following example congures 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.
NOTE
: Do not run VRRP version 2 and version 3 in the same group for an extended period of time
Example: Migrating an IPv4 VRRP Group from VRRPv2 to VRRPv3
NOTE
: Carefully following this procedure, otherwise you might introduce dual master switches issues.
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.
