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.
Example
Dell(conf-if-te-0/0-vrid-100)#version ?
2 VRRPv2
3 VRRPv3
both Interoperable, send VRRPv3 receive both
Dell(conf-if-te-0/0-vrid-100)#version 3
virtual-address
Configure up to 12 IP addresses of virtual routers in the VRRP group. To start sending VRRP packets, set at least one virtual
address for the VRRP group.
C9000 Series
Syntax
virtual-address ip-address1 [... ip-address12]
To delete one or more virtual IP addresses, use the no virtual-address ip-address1 [...
ip-address12] command.
Parameters
ip-address1 Enter an IP address of the virtual router in dotted decimal format. The IP address
must be on the same subnet as the interface’s primary IP address.
... ip-address12 (OPTIONAL) Enter up to 11 additional IP addresses of virtual routers in dotted
decimal format. Separate the IP addresses with a space. The IP addresses must be
on the same subnet as the interface’s primary IP address.
