MPLS in IP - IP Protocol

This page provides IP protocol information on the MPLS in IP IP protocol (MPLS-in-IP) detected by the Netify DPI engine. Please see the IP protocol catalog for information on other IP protocols.

MPLS-in-IP carries MPLS-labeled packets directly encapsulated within IP, letting MPLS traffic cross IP-only network segments that lack native MPLS support.

IP Protocol Network Policy

MPLS-in-IP carries MPLS-labeled traffic across IP-only network segments lacking native MPLS support, and is relevant only to service-provider networks bridging MPLS domains.
