Cisco MWR 1941-DC Router with the Cisco IOS IP-RAN Feature Set
To configure HRSP, use the following commands while in interface configuration mode:
Command
Step 1
Router(config-if)# standby group name group-name
Step 2
Router(config-if)# standby group ip address
Step 3
Router(config-if)# standby group timers [msec]
hellotime [msec] holdtime
Step 4
Router(config-if)# standby group preempt
Purpose
Specifies the name of the standby group.
Note The standby group names must be "one" and
"two." For FE 0/0, the command must be
standby 1 name one. For FE 0/1, the
command must be standby 2 name two.
If you omit the group-name or if you enter a
Tip
group name that doesn't begin with one or
two, the configuration will fail and there will
be a mismatch in the information displayed
by the show redundancy and show standby
commands.
Enables HSRP and assigns an IP address to the
virtual router. This address is the same for both the
active and standby routers.
Configures the time between hello packets and the
time before other routers declare the active Hot
Standby or standby router to be down.
You must use 1 for the hello time and 3 for
Note
the hold time.
Indicates that the router can become the active router
when its priority is higher than all other
HSRP-configured routers. Without preemption, a
standby router will only transition to the active state
if HSRP "hello messages" cease.
In the CDMA IP-RAN solution, there may be
situations in which you want a switchover to occur in
the absence of a router or FE failure, therefore,
preemption is required.
