Page 812: Interface, Preempt, Mode, Priority
54-3
Switch(Config-Router)#enable
54.6 interface
Commands: interface {IFNAME | Vlan <ID>}
no interface
Function: Configures the VRRP interface.
Parameters: IFNAME: Interface name, for example “VLAN1”.
Vlan <ID>: VLAN ID.
Default: Not configured by default.
Command mode: VRRP protocol configuration mode
Usage Guide: This command adds a layer 3 interface to an existing Standby cluster. The "no interface"
command removes the L3 interface from the specified Standby cluster.
Example: Configuring the interface as "interface vlan 1".
Switch(config-router)#router vrrp 10
Switch(Config-router)#interface vlan 1
54.7 preempt-mode
Commands: preempt-mode {true | false}
Function: Configures the preemptive mode for VRRP.
Parameters: N/A.
Command mode: VRRP protocol configuration mode
Default: Preemptive mode is set by default.
Usage Guide: If a router (or L3 Ethernet switch) requiring high priority needs to preemptively become the
active router (or L3 Ethernet switch), the preemptive mode should be enabled.
Example: Setting non-preemptive VRRP mode.
Switch(Config-Router-Vrrp)#preempt-mode false
54.8 priority
Commands: priority <value>
Function: Configures VRRP priority.
Parameters:
Default: The priority of all backup routers (or L3 Ethernet switch) in a Standby cluster is 100.
Command mode: VRRP protocol configuration mode
Usage Guide: Priority determines the ranking of a router (or L3 Ethernet switch) in a Standby cluster, the
higher priority the more likely to become the Master. When a router (or L3 Ethernet switch) is configured
as Master dummy IP address, its priority is always 254 and does not allow modification. When 2 or more
routers (or L3 Ethernet switch) with the same priority value present in a Standby cluster, the router (or L3
Ethernet switch) with the greatest VLAN interface IP address becomes the Master.
Example: Setting VRRP priority to 150.
Switch(Config-Router-Vrrp)# priority 150
