Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 15
To configure the name of the standby group, use the
standby name
command in interface configuration
mode. To disable the name, use the
no
form of this command.
Router(config-if)#
standby
[
group-number
]
name
[
group-name
]
Where:
•
group-number
—Specifies the standby group number.
•
group-name
—Specifies the name of the standby group.
For example, the following command specifies the hot standby group name as
one
:
Router(config-if)#
standby 1 name_one
Note
Typically, only one GE is used in a RAN-O solution. So, the command must be
standby 1
name_one
.
Caution
If you omit the
group-name
or if you enter a group name that does not 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.
Step 16
To configure HSRP to track an object and change the Hot Standby priority based on the state of the
object, use the
standby track
command in interface configuration mode. To remove the tracking, use
the
no
form of this command.
Note
When you use the Cisco 3825 router in a RAN-O solution, you must configure the GE interface
to track the multilink interface and the loopback interface.
Router(config-if)#
standby
[group-number]
track
interface-type interface-number
[
interface-priority
]
Where:
•
group-number
—(Optional) Group number to which the tracking applies.
•
interface-type
—Interface type (combined with interface number) that will be tracked.
•
interface-number
—Interface number (combined with interface type) that will be tracked.
•
interface-priority
—(Optional) Amount by which the Hot Standby priority for the router is
decremented (or incremented) when the interface goes down (or comes back up). The default value
is 10.
For example, the following command specifies the hot standby group 1 to track Loopback 103 interface:
Router(config-if)#
standby 1 track Loopback103
Note
In redundant configurations, you should issue
standby track
commands for both the health
interface (loopback101), the revertive interface (loopback102), the backhaul interface
(multilink1), and shorthaul interface (loopback 103). The decrement values
must
be as follows:
10 for the multilink, GE, and health interfaces; 5 for the revertive interface.
