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-id md5 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-map map-name}]}
