Group version
Congure a VRRP version for the system. Dene either VRRPv2 — vrrp version 2 or VRRPv3 — vrrp version 3.
• Congure the VRRP version for IPv4 in INTERFACE mode.
vrrp version
Congure VRRP version 3
OS10(config)# vrrp version 3
1 Set the switch with the lowest priority to vrrp version 2.
2 Set the switch with the highest priority to vrrp version 3.
3 Set all switches from vrrp version 2 to vrrp version 3.
Migrate IPv4 group from VRRPv2 to VRRPv3
OS10_backup_switch1(config)# vrrp version 2
OS10_backup_switch2(config)# vrrp version 2
Set master switch to VRRPv3
OS10_master_switch(config)# vrrp version 3
Set backup switches to VRRPv3
OS10_backup_switch1(config)# vrrp version 3
OS10_backup_switch2(config)# vrrp 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 you congure multiple VRRP groups on an interface, only one of the VRRP groups can contain the interface primary or secondary IP
address.
