Usage guidelines
When IPHC TCP applies to MP links, the associated VA interfaces perform the compression. You can
check the compression information on MP templates, such as VT or dialer interfaces.
When IPHC TCP applies to normal PPP links, physical interfaces perform the compression. You can check
the compression information on the physical interfaces.
