    abstract =  {RFC 6514 created a space of Tunnel Type code points for a new BGP attribute called the "P-Multicast Service Interface Tunnel (PMSI Tunnel) attribute". However the RFC did not create an IANA registry for these. There now is need to make further code point allocations from this name space. This document serves to update RFC 65124 in that it creates an IANA registry for that purpose.},
