PIM Message Type Space Extension and Reserved Bits
RFC 9436, “PIM Message Type Space Extension and Reserved Bits”, is a Proposed Standard document published in August 2023 by S. Venaas, A. Retana. It updates RFC 3973, RFC 5015, RFC 5059, RFC 6754, RFC 7761, RFC 8364. It obsoletes RFC 8736. The canonical text is published by the RFC Editor.
Abstract
The PIM version 2 messages share a common message header format. The common header definition contains eight reserved bits. This document specifies how these bits may be used by individual message types and extends the PIM type space.
This document updates RFCs 7761 and 3973 by defining the use of the Reserved field in the PIM common header. This document further updates RFCs 7761 and 3973, along with RFCs 5015, 5059, 6754, and 8364, by specifying the use of the bits for each PIM message.
This document obsoletes RFC 8736.
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.
