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
you configured and tracked in
. (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

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.

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
