Hi, To bring draft-ietf-trill-clear-correct, currently in WG Last Call, more closely in alignment with draft-eastlake-isis-rfc6326bis, I propose to add to the clear-correct draft a small new Section 3.3 as follows: 3.3 IP Address Based Multicast Pruning The TRILL base protocol specification [RFC6325] provides for and recommends the pruning of multi-destination frame distribution trees based on the location of IP multicast routers and listeners; however, multicast listening is identified by derived MAC adddresses as communicated in the Group MAC Address sub-TLV [RFC6326bis]. TRILL Switches MAY communicate multicast listeners and prune distribution trees based on the actual IPv4 or IPv6 addresses involved. Additional Group Address sub-TLVs are provided in [RFC6326bis] to carry this information. A TRILL Switch that is only capable of pruning based on derived MAC address SHOULD calculate and use such derived MAC addresses from multicast listener IPv4/IPv6 address information it receives.
