The Branch Gateway offers two options for configuring header compression:
IP Header compression (IPHC) method, as defined by RFC 2507. IPHC-type compression applies to RTP, TCP, and UDP headers.
Van Jacobson (VJ) method, as defined in RFC 1144. VJ compression applies to TCP headers only.
Note:
VJ compression and IPHC cannot co-exist on an interface, and IPHC always overrides VJ compression. Thus, if you define both VJ compression and IPHC, only IPHC is enabled on the interface regardless of the order of definition.
