Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference
Unicast or Multicast RTP Packets
This command can compress unicast or multicast RTP packets, and, hence, multicast backbone
(MBONE) traffic can also be compressed over slow links. The compression scheme is beneficial only
when you have small payload sizes, as in audio traffic.
Examples
The following example enables RTP header compression on the Serial1/0/0 interface and limits the
number of RTP header compression connections to 10. In this example, the optional iphc-format
keyword of the ip rtp header-compression command is specified.
Router> enable
Router# configure terminal
Router(config)# interface Serial1/0/0
Router(config-if)# encapsulation ppp
Router(config-if)# ip rtp header-compression iphc-format
Router(config-if)# ip rtp compression-connections 10
Router(config-if)# exit
The following example enables RTP header compression on the Serial1/0/0 interface and limits the
number of RTP header compression connections to 20. In this example, the optional iphc-format
keyword of the ip rtp header-compression command is specified.
Router> enable
Router# configure terminal
Router(config)# interface Serial1/0/0
Router(config-if)# encapsulation ppp
Router(config-if)# ip rtp header-compression iphc-format
Router(config-if)# ip rtp compression-connections 20
Router(config-if)# exit
In the following example, RTP header compression is enabled on the Serial1/0/0 interface and the
optional periodic-refresh keyword of the ip rtp header-compression command is specified:
Router> enable
Router# configure terminal
Router(config)# interface Serial1/0/0
Router(config-if)# encapsulation ppp
Router(config-if)# ip rtp header-compression iphc-format periodic-refresh
Router(config-if)# ip rtp compression-connections 10
Router(config-if)# exit
