Chapter 14 Configuring Automatic Protection Switching
Configuring MR-APS with Static Routes on Channelized Line Cards
To optionally configure MR-APS with static routes on channelized line cards, enter the following
commands beginning in global configuration mode:
Command
Step 1
Router(config)# redundancy
Step 2
Router(config-r)# associate slot slot-one
mr-aps
Step 3
Router(config-r)# exit
Step 4
Router(config)# ip route prefix mask
{ip-address | interface-type interface-number
[ip-address]} [distance] [name] [permanent]
[tag tag]
Step 5
Router(config)# controller SONET
slot#/subslot#/port#
Step 6
Router(config-controller)# ip route static
update immediate
Step 7
Router(config-controller)# carrier-delay
[seconds | msec seconds]
Step 8
Router(config-controller)# aps group
group-number
Step 9
Router(config-controller)# aps working
circuit-number
Step 10
Router(config-controller)# exit
Step 11
Repeat steps 1 through 8 on the second router to configure the protect interface. Substitute the appropriate slot
numbers, IP addresses, interface types, and interface numbers. After you complete step 8, go to step 12.
Step 12
Router(config-controller)# aps protect
circuit-number ip-address
Step 13
Router(config-controller)# exit

Multirouter Automatic Protection Switching
Purpose
Enters redundancy configuration mode, which allows you
to associate two line cards as a redundant pair.
Logically associates slots for APS processor redundancy.
To allow MR-APS to operate, you must associate a slot on
the working interface of one router and with a
corresponding protect interface on a second router.
Exits redundancy configuration mode and returns to global
configuration mode.
Configures a static IP address.
When configuring APS, we recommend that you specify the
optional IP address of the interface to improve routing
performance.
Specifies the interface type and number. Enters controller
configuration mode.
(Optional) Specifies that static routes will be added to the
routing table immediately after the interface becomes
active.
Sets the carrier delay timer value in seconds or
milliseconds.
This command allows you to filter link outages and to not
report them as a link down event if they occur before the
carrier delay timer expires. In MR-APS, system
performance can be enhanced if link-down event messages
are kept to a minimum.
Permits more than one APS protect and working interface
to be supported on a router.
Configures an interface as a working interface.
Exits controller configuration mode and returns to global
configuration mode.
Configures an interface as a protect interface.
The ip-address argument specifies the IP address of the
router that has the working interface.
Exits controller configuration mode and returns to global
configuration mode.
