Use the
undo ip tcp vjcompress
command to disable the PPP interface to compress
the VJ TCP header.
If the VJ TCP header is permitted to compress at the PPP interface, the interface at the
opposite end shall also permit to compress the VJ TCP header. This command is only
used in the centralized environment.
By default, the VJ TCP header is disabled to compress at the PPP interface.

command to disable IP header compression.
IP header compression discussed here refers to compression of TCP and RTP
headers.
By default, TCP header compression and RTP header compression are disabled on the
interface.
The compression command can take effect on a link only when it is configured at both
ends of the link.
The configuration will take effect only when the
shutdown

shutdown

undo shutdown
operations should be performed on all the MPs.
