Usage 
Information
You can use the version both command to migrate from VRRPv2 to VRRPv3. When 
you set the VRRP protocol version to both, the switch sends only VRRPv3 
advertisements but can receive either 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.
