DNS Reverse IP Automatic Multicast Tunneling Discovery
RFC 8777, “DNS Reverse IP Automatic Multicast Tunneling Discovery”, is a Proposed Standard document published in April 2020 by J. Holland. It updates RFC 7450. The canonical text is published by the RFC Editor.
Abstract
This document updates RFC 7450, "Automatic Multicast Tunneling" (or AMT), by modifying the relay discovery process. A new DNS resource record named AMTRELAY is defined for publishing AMT relays for source-specific multicast channels. The reverse IP DNS zone for a multicast sender's IP address is configured to use AMTRELAY resource records to advertise a set of AMT relays that can receive and forward multicast traffic from that sender over an AMT tunnel. Other extensions and clarifications to the relay discovery process are also defined.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
