8.10 Configuring frame relay IP header compression
8.10.1 Establishing the configuration task
Applicable environment
The FR feature provides the IP header compression (IPHC) function, including the
compression of RTP/TCP header. You can specify the RTP header compression on the
interface or specify the TCP/IP header compression when you configure the static address
mapping.
FR P2P sub-interfaces do not support FR IPHC.
Preconfiguration tasks
Before configuring FR over an IP network and IPHC, complete the following tasks:
• Configuring physical parameters for FR interfaces
• Configuring FR interfaces
Data preparation
To configure IPHC, you need the following data.
No Data
1 FR interface number of a router, IP addresses to be allocated and the VC number
2 Number of RTP compression connections or the number of TCP compression
connections
