[RFC6513] and [RFC6514] specify MVPN Inter-AS Segmentation procedures. [RFC7524] specifies MVPN Inter-Area Segmentation procedures. [I-D.ietf-bess-evpn-bum-procedure-updates] specifies EVPN BUM Inter-Region Segmentation Procedures. Several other documents also touch upon the segmentation topic. The forwarding at the segmentation points has been assumed to be label switching, subject to certain limitations. The purpose of this document is to provide a review of segmentation points' available forwarding options and limitations, and to clarify and expand some procedures.
