Cisco Systems 78-13983-04 manual Configuring Multilink Interfaces, Enabling the FE Interface

Chapter 4 Configuring with the Command-Line Interface

Configuring Multilink Interfaces

Step 5 Specify other interfaces on the router for the HSRP process to monitor in order to alter the HSRP priority for a given group. When using the MWR 1900 router in the CDMA IP-RAN solution, you must configure each FE interface to track the multilink interface, the loopback interfaces, and the other FE interface.

Router(config-if)#standby group track multilinknumber decrement_value

Router(config-if)#standby group track loopbacknumber decrement_value

Router(config-if)#standby group track fastethernetnumber decrement_value

Note In redundant configurations, you should issue standby track commands for both the health interface (loopback101) and the revertive interface (loopback102) as well as for the backhaul interface (multilink1). The decrement values must be as follows: 10 for the multilink, FE, and health interfaces; 5 for the revertive interface.

Step 6 Specify a priority of 100.

Router(config-if)#standby group priority 100

Note If you are using the MWR 1900 in a redundant configuration, you must also set the keepalives under the FE interface to 1.

Router(config-if)# keepalive 1

Enabling the FE Interface

Once you have configured the FE interface, enable it by doing the following while still in interface configuration mode:

Step 1 Enable the interface.

Router(config-if)# no shutdown

Configuring Multilink Interfaces

To configure the multilink interfaces, complete the following tasks:

•Configuring Multilink PPP

•Configuring IP Address Assignment

•Configuring PPP Multiplexing

•Configuring RTP/UDP Compression

•Configuring Routing Protocol Attributes

•Configuring PIM
