Chapter 14 Configuring Automatic Protection Switching Multirouter 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 Purpose Step 1 Router(config)# redundancy Enters redundancy configuration mode, which allows you to associate two line cards as a redundant pair. Step 2 Router(config-r)# associate slot slot-one mr-aps 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. Step 3 Router(config-r)# exit Exits redundancy configuration mode and returns to global configuration mode. 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)# controller SONET slot#/subslot#/port# Specifies the interface type and number. Enters controller configuration mode. Step 6 Router(config-controller)# 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-controller)# 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-controller)# aps group group-number Permits more than one APS protect and working interface to be supported on a router. Step 9 Router(config-controller)# aps working circuit-number Configures an interface as a working interface. Step 10 Router(config-controller)# exit Exits controller 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-controller)# 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-controller)# exit Exits controller configuration mode and returns to global configuration mode. OL-2226-23 Cisco 10000 Series Router Software Configuration Guide 14-25
