The draft-ietf-roll-admin-local-policy is in RFC-editor queue, and the editor had some difficulties with some of the sentences and there was some significant back and forth with the authors to make sure the sense was correct. I want to first publically thank Lynne Bartholomew, Peter van der Stok and Robert Craigie for their perseverance on this. This "short" document is now two years in the making, in part due to queuing issues with trickle-mcast, etc. These are the changes that will be made, and I hope I got the last set of them! I am posting this in order to determine that there are no *serious* and VERY *significant* objections. We have been through this many times already. Michael and Ines. Original: o The message carries an MPL option (MPL message) and the incoming MPL interface is subscribed to the destination multicast address. o The message does not carry an MPL option, the multicast address is unequal to ALL_MPL_FORWARDERS scope 4 or scope 3, and the interface has expressed interest to receive messages with the specified multicast address via MLD [RFC3810] or via IGMP [RFC3376]. The message was sent on according to PIM-DM [RFC3973] or according to PIM-SM [RFC4601]. Replace by : o The message carries an MPL option (MPL message) and the incoming MPL interface is subscribed to the destination multicast address. [MCR: unchanged, I think] o The message does not carry an MPL option and the interface has expressed interest to receive messages with the specified multicast address via MLD [RFC3810] or via IGMP [RFC3376]. The message was sent on according to PIM-DM [RFC3973] or according to PIM-SM [RFC4601]. ============= Original: Two types of legal multicast messages are considered: (1) MPL messages, and (2) multicast messages which do not carry the MPL option Replace by: Two types of legal multicast messages are considered in Section 4.1: (1) MPL messages, and (2) multicast messages which do not carry the MPL option ============= Original: o MPL messages with a multicast scope of 5 or higher MUST encapsulate a message with the same multicast address without MPL option. The decapsulated message can be forwarded over an interface when the interface is subscribed with MLD to the same multicast address. Replace by: o MPL messages which encapsulate a message with a multicast scope of 5 or higher are decapsulated and forwarded over the interface when the interface is subscribed to the multicast address of the decapsulated message. ============= Original: o Link-local (scope 2) messages or realm-local (scope 3) multicast messages are not forwarded. o Admin-local (scope 4) multicast messages are encapsulated with a header carrying the MPL option and are forwarded on al MPL interfaces that are subscribed to the multicast address, have the same zone index, have PROACTIVE_FORWARDING set to true, and have MPL_BLOCKED set to false. Replace by: o Link-local (scope 2), realm-local (scope 3) and admin-local (scope 4) multicast messages are not forwarded. ============= Original: o Multicast messages with a multicast scope of 5 or higher are encapsulated with a header carrying the MPL option and are forwarded on al MPL interfaces that are subscribed to the multicast address, have PROACTIVE_FORWARDING set to true, and have MPL_BLOCKED set to false. In addition these messages follow the Multicast forwarding rules as specified by PIM [RFC3973], [RFC4601] according to group specifications enabled by MLD [RFC3810] or IGMP [RFC3376]. Replace by: o Multicast messages with a multicast scope of 5 or higher are encapsulated in a MPL message with destination address ALL_MPL_FORWARDERS scope 4. The resulting message is then treated as described in section 4.2.1. -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works IETF ROLL WG co-chair. http://datatracker.ietf.org/wg/roll/charter/ -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works IETF ROLL WG co-chair. http://datatracker.ietf.org/wg/roll/charter/
