Enabling RTP Header Compression on a Serial Interface
To enable RTP header compression for serial encapsulation HDLC or PPP, use the following command
in interface configuration mode:
If you include the passive keyword, the software compresses outgoing RTP packets only if incoming
RTP packets on the same interface are compressed. If you use the command without the passive
keyword, the software compresses all RTP traffic.
See the “RTP Header Compression Examples” section later in this chapter for an example of how to
enable RTP header compression on a serial interface.
Enabling RTP Header Compression with Frame Relay Encapsulation
To enable RTP header compression with Frame Relay encapsulation, use the following commands in
interface configuration mode as needed:
See the “RTP Header Compression Examples” section later in this chapter for an example of how to
enable RTP header compression with Frame Relay encapsulation.
To disable RTP and TCP header compression with Frame Relay encapsulation, use the following
command in interface configuration mode:
Changing the Number of Header Compression Connections
For Frame Relay encapsulation, the software does not specify a maximum number of RTP header
compression connections. You can configure from 3 to 256 RTP header compression connections on an
interface.
Command Purpose
Router(config-if)# ip rtp header-compression
[passive]
Enables RTP header compression.
Command Purpose
Router(config-if)# frame-relay ip rtp
header-compression [passive]
Enables RTP header compression on the physical interface, and
all the interface maps inherit it. Subsequently, all maps will
perform RTP/IP header compression.
Router(config-if)# frame-relay map ip ip-address
dlci [broadcast] rtp header-compression [active |
passive] [connections number]
Enables RTP header compression only on the particular map
specified.
Router(config-if)# frame-relay map ip ip-address
dlci [broadcast] compress [active | passive]
[connections number]
Enables both RTP and TCP header compression on this link.
Command Purpose
Router(config-if)# frame-relay map ip ip-address
dlci [broadcast] nocompress
Disables both RTP and TCP header compression on this link.
