Virtual IP—Primary virtual IP address of the HSRP group. If this address is not configured, the
agent attempts to discover the virtual address through a discovery process which scans the hello
messages.
• Preempt—If enabled, the current router attempts to overthrow a lower priority active router and
attempts to become the active router. If disabled, this router becomes the active router only if there
is no such router or the active router fails.
–
true—Preempt enabled.
– false—Preempt disabled.
•
Delay Minimum—Time difference (in seconds) between a router power up and the time it can start
preempting the currently active router. This value is only applicable when preemption is enabled.
• Priority—Metric used to select the active and standby routers. 0 is lowest priority, 255 is highest.
Router with highest priority is selected to be the active router.
•

the active router.

the active router.
