Chapter 4 Configuring with the Command-Line Interface

Configuring Multilink Interfaces

To configure RTP header compression, do the following while still in multilink interface configuration mode:

Step 1 Enable RTP header compression for serial encapsulations:

RPM-3(config-if)#ip rtp header-compression

Step 2 By default, the software supports a total of 16 RTP header compression connections on an interface. To change that number, enter the following command:

RPM-3(config-if)#ip rtp compression-connections number

Note The MWR 1900 supports up to 600 RTP header compression connections on an interface.

Configuring Routing Protocol Attributes

When used in the CDMA IP-RAN solution, the multilink interface must be configured to support the OSPF routing protocol.

To configure OSPF routing protocol attributes, do the following while still in interface configuration mode:

Step 1 Enable OSPF Message Digest 5 (MD5) authentication:

RPM-3(config-if)#ip ospf message-digest-key key-idmd5 key

Step 2 Specify the interval between hello packets that the Cisco IOS software sends on the interface:

RPM-3(config-if)#ip ospf hello-interval seconds

Step 3 Set the interval at which hello packets must not be seen before neighbors declare the router down:

RPM-3(config-if)#ip ospf dead-interval seconds

Configuring PIM

Because the MWR 1900 is used in a multicast PPP environment, you should configure the PIM mode of the multilink interface.

To configure the PIM mode, do the following while still in interface configuration mode:

Step 1 Enter the following command:

RPM-3(config-if)#ip pim {sparse-mode sparse-dense-mode dense-mode [proxy-register

{list access-list route-mapmap-name}]}
