Reference Guide

Use the version both command in Conguration mode to migrate from VRRPv2 to VRRPv3. When you set the VRRP version to
version both, the switch sends only VRRPv3 advertisements but can receive VRRPv2 or VRRPv3 packets.
1 Set the switch with the lowest priority to version both.
2 Set the switch with the highest priority to version 3.
3 Set all switches from version both to version 3.

Virtual IP addresses
Virtual routers contain virtual IP addresses congured for that VRRP group (VRID). A VRRP group does not transmit VRRP packets until
you assign the virtual IP address to the VRRP group.
To activate a VRRP group on an interface, congure at least one virtual IP address for a VRRP group. The virtual IP address is the IP
address of the virtual router and does not require an IP address mask. You can congure up to 10 virtual IP addresses on a single VRRP
group (VRID).
These rules apply to virtual IP addresses:
• The virtual IP addresses must be in the same subnet as the primary or secondary IP addresses congured on the interface. Though a
single VRRP group can contain virtual IP addresses belonging to multiple IP subnets congured on the interface, Dell EMC recommends
conguring virtual IP addresses belonging to the same IP subnet for any one VRRP group. An interface on which you enable VRRP
contains a primary IP address of 50.1.1.1/24 and a secondary IP address of 60.1.1.1/24. The VRRP group (VRID 1) must contain virtual
addresses belonging to subnet 50.1.1.0/24 or subnet 60.1.1.0/24.
• If the virtual IP address and the interface’s primary/secondary IP address are the same, the priority of the VRRP group is set to 255 by
default. The interface then becomes the owner router of the VRRP group and the interface’s physical MAC address changes to that of
the owner VRRP group’s MAC address.
• If you congure multiple VRRP groups on an interface, only one of the VRRP groups can contain the interface primary or secondary IP
address.
Congure virtual IP address
Congure the virtual IP address — the primary IP address and the virtual IP addresses must be on the same subnet.
1 Congure a VRRP group in INTERFACE mode (1 to 255).
vrrp-group vrrp-id
2 Congure virtual IP addresses for this VRRP ID in INTERFACE-VRRP mode (up to 10 IP addresses).
