Description RTP is connection oriented; the number of RTP connections that a link can
accommodate is relatively large. The use of compression however requires the router
to maintain some information for each connection when compressing headers. To
restrict the memory load generated by compression, you can use the
ppp
compression iphc rtp-connections
command to limit the number of
compression-enabled RTP connections to three for example. The packets on the
fourth RTP connection are not compressed as a result.
The configuration will take effect after commands shutdown and undo shutdown
have been executed on the interface. When configuring MP, commands shutdown
and undo shutdown must be executed on all MP member interfaces
