17.2.2.7 vrrp authentication string
Command: ip vrrp authentication string <string>
no ip vrrp authentication string
Function: Set the authentication string of the VRRP packets sent on the interface; the “no
ip vrrp authentication string” command restores the default authentication string.
Parameter: <string> is the authentication string.
Command mode: Interface Mode
Default: There is no authentication string by default.
Usage Guide: This command is used to avoid the interference of non-group members. If
all the routers in the same standby group are set to the plain text authentication
mode, they have to use the same authentication string.
Example: Set the authentication string to public
Switch(config)#interface vlan 1
Switch(Config-If-Vlan1)# ip vrrp authentication string public

Command: preempt-mode{true| false}
Function: Configure the VRRP preempt mode.

Default: The preempt mode is enable by default.
Usage Guide: If users want to configure the router (or the layer3 switch) with high priority
to preempt the master router, this feature should be enabled.
Example: Disable the preempt mode.
Switch(Config-Router-Vrrp)# preempt-mode false
17.2.2.9 priority
