Chapter 4 Configuring the MWR 1941-DC in an IP-RAN

Configuring Loopback Interfaces

Configuring Loopback Interfaces

The loopback interface is a software-only, virtual interface that emulates an interface that is always up.
The interface-number is the number of the loopback interface that you want to create or configure. There
is no limit on the number of loopback interfaces you can create.

The multilink interface is a virtual interface, if you are

not

going to assign an explicit IP address to the

interface, you should create a loopback interface for the multilink interface to enable IP processing on
the interface.

In the case where the MWR 1941-DC is used in a redundant configuration, you must also configure
loopback interfaces for the health and revertive interfaces. The health interface monitors the status of the
redundant configuration so that the standby router can take over if there is a problem with the active
router. The revertive interface is required to ensure that the switchover takes place. We recommend that
you use 101 for the health interface and 102 for the revertive interface.

To configure a loopback interface, do the following beginning in global configuration mode:

Step 1

Create a loopback interface for each multilink interface:

Router(config)#

interface loopback

number

Router(config-if)#

ip address

ip_address subnet_mask

Note

For the health and revertive interfaces, you do not need to assign an IP address.

Step 2

Exit interface configuration mode:

Router(config-if)#

exit

Configuring Fast Ethernet Interfaces

To configure the FE interface of the MWR 1941-DC, complete the following tasks:

•

Configuring the FE Interface IP Address

•

Setting the Speed and Duplex Mode

•

Configuring Routing Protocol Attributes

•

Configuring PIM

•

Configuring HSRP Support

•

Enabling the FE Interface
