Step 4
Router(config)# ip route prefix mask
{ip-address | interface-type interface-number
[ip-address]} [distance] [name] [permanent]
[tag tag]
Configures a static IP address.
When configuring APS, we recommend that you specify the
optional IP address of the interface to improve routing
performance.
Step 5
Router(config)# interface type number
Specifies the interface type and number. Enters interface
configuration mode or controller configuration mode.
Step 6
Router(config-if)# ip route static update
immediate
(Optional) Specifies that static routes will be added to the
routing table immediately after the interface becomes
active.
Step 7
Router(config-if)# carrier-delay [seconds |
msec seconds]
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.
Step 8
Router(config-if)# aps group group-number
Permits more than one APS protect and working interface
to be supported on a router.
Step 9
Router(config-if)# aps working circuit-number
Configures an interface as a working interface.
Step 10
Router(config-if)# exit
Exits interface configuration mode and returns to global
configuration mode.
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-if)# aps protect circuit-number
ip-address
Configures an interface as a protect interface.
The ip-address argument specifies the IP address of the
router that has the working interface.
Step 13
Router(config-if)# exit
Exits interface configuration mode and returns to global
configuration mode.
