Vrrp Vrid Preempt-Mode - 3Com 3C13618 Command Reference Manual

3Com Router Command Reference — V1.00
VRRP stipulates that the backup groups of an interface should use the same
authentication type and authentication key. Therefore, after the command is
configured on an Ethernet interface, all the VRRP backup groups on the interface will
enable authentication.
In addition, the members in the same backup group should have the same
authentication type and authentication key.
Example
# Set the authentication types and authentication keys of all VRRP backup groups at
interface Ethernet 0.

Description
Using the vrrp vrid preempt-mode command, you can configure the preemption
mode and delay time of routers in a VRRP backup group. Using the undo vrrp vrid
preempt-mode command, you can restore the default value of the preemption mode
and delay time.
By default, preempt without delay.
If a router with a higher priority is needed to actively preempt as the MASTER, the
router should be set to preemption mode. If more time is needed for preemption, the
delay time can be set.
