Chapter 4 Configuring with the Command-Line Interface

Configuring Redundancy

Step 4 Specify the loopback interface to be used to monitor the health of the router and for revertive purposes.

Router(config-r-y)#standby use-interface interface health

Router(config-r-y)#standby use-interface interface revertive

Note The interfaces that you specify for the health and revertive interfaces should match those that you configured and tracked in Configuring Loopback Interfaces. (We recommend you use loopback101 for the health and loopback102 for the revertive interface).

Step 5 Specify the interface to be used for backhauling.

Router(config-r-y)#standby use-interface interface backhaul

Note The interface that you specify for the backhaul must be an MLPPP interface. If you want to use a serial interface as the backhaul, you must first configure that interface to be part of an MLPPP bundle. The interface that you specify for the backhaul interface should match one of those that you configured and tracked in Configuring Loopback Interfaces.

Step 6 Exit y-mode configuration mode.

Router(config-r-y)# exit

To verify the status of the relays on an MWR 1900 router, use the show controllers command.

Stand-Alone MWR 1900

The MWR 1900 router has relays that work with a special “y” cable for redundancy and are controlled by HSRP. You can, however, use the MWR 1900 as a stand-alone device. If you choose not to use the MWR 1900 in a redundant configuration, you should not configure HSRP and you must control the relays of the VWIC card manually.

To manually set the relays to open or closed, do the following starting in global configuration mode:

Step 1 Enter redundancy mode.

Router(config)# redundancy

Step 2 Enter the y-cable mode.

Router(config-r)# mode y-cable

Step 3 Specify that the router is to be used as a stand-alone device. This command closes the relays.

Router(config-r-y)# standalone

Step 4 Exit y-mode configuration mode.

Router(config-r-y)# exit

To verify the status of the relays on an MWR 1900 router, use the show controllers command.
