MVPN

[sergeyrar]

Does anyone have any idea what is the difference between SAFI 5 and SAFI 129?

"   This document defines a new NLRI, called "MCAST-VPN", to be carried
    in BGP using multiprotocol extensions.  It has been assigned SAFI 5.
    Also, SAFI 129 has been assigned to "Multicast for BGP/MPLS IP
    Virtual Private Networks (VPNs)".   "

SAFI 129 seems to be used for UMH selection, and SAFI 5 for MVPN peer discovery and other functions...
But its confusing why there are two different SAFIs for this.

Please help
