R0106-HP MSR Router Series Layer 2 - WAN Command Reference(V7)

• If VT interfaces, dialer interfaces, or ISDN interfaces are used, the associated VA interfaces perform

IPHC. You can view the compression information on the VA interfaces.

• If MP-group interfaces are used, the MP-group interfaces perform IPHC. You can view the

compression information on the MP-group interfaces.

When IPHC applies to normal PPP links, physical interfaces perform IPHC. You can view the compression

information on the physical interfaces.
