Create virtual router
VRRP uses the VRID to identify each virtual router congured. Before using VRRP, you must congure the interface with the primary IP
address and enable it.
• Create a virtual router for the interface with the VRRP identier in INTERFACE mode (1 to 255).
vrrp-group vrrp-id
• Delete a VRRP group in INTERFACE mode.
no vrrp-group vrrp-id
Congure VRRP
OS10(config)# interface ethernet 1/1/5
OS10(conf-if-eth1/1/5)# vrrp-group 254
Verify VRRP
OS10(conf-eth1/1/5-vrid-254)# do show running-configuration
...
!
interface ethernet 1/1/5
ip address 10.10.10.1/24
!
vrrp-group 254
no shutdown
...
Group version
Congure a VRRP version for the system. Dene either VRRPv2 — vrrp version 2, VRRPv3 — vrrp version 3, or vrrp
version both to migrate a system from VRRPv2 to VRRPv3.
• Congure the VRRP version for IPv4 in INTERFACE mode.
vrrp version
Congure VRRP version 3
OS10(config)# vrrp version 3
Use the vrrp version both command in Conguration mode to migrate from VRRPv2 to VRRPv3. When you set the VRRP version
to
vrrp version both, the switch sends and receives both VRRPv2 or VRRPv3 packets.
1 Set the switch with the lowest priority to vrrp version both.
2 Set the switch with the highest priority to vrrp version 3.
3 Set all switches from vrrp version both to vrrp version 3.
Migrate IPv4 group from VRRPv2 to VRRPv3
OS10_backup_switch1(config)# vrrp version both
OS10_backup_switch2(config)# vrrp version both
Set master switch to VRRPv3
OS10_master_switch(config)# vrrp version 3
