Abstract
This document enumerates several common IANA allocations for use by
Mobile Ad hoc NETwork (MANET) protocols. The following well-known
numbers are required: a UDP port number, an IP protocol number, and a
link-local multicast group address.

Introduction This document enumerates several common IANA allocations for use by one or more protocols that conform to [RFC5444]. The following well-known numbers are required: a UDP port number, an IP protocol number, and a link-local multicast group address. All interoperable protocols running on these well-known IANA allocations MUST conform to [RFC5444]. [RFC5444] provides a common format that enables one or more protocols to share the IANA allocations defined in this document unambiguously. 2. Conventions Used in This Document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 3. UDP Port Number MANET routers require a well-known UDP port number [IANA] to send and receive MANET routing protocol packets. The title of this UDP port is "manet". The value of this UDP port is 269. 4. IP Protocol Number MANET routers require a well-known IP protocol number [IANA] to send and receive MANET routing protocol packets. The title of this IP protocol number is "manet". The value of this IP protocol number is 138. Chakeres Standards Track [Page 2]
RFC 5498 IANA Allocations for MANET Protocols March 2009 5. Link-Local Multicast Group for MANET Routers MANET routers require a well-known, link-local multicast address [RFC4291] to send and receive MANET routing protocol packets. The name of the multicast address to reach link-local (LL) MANET routers is "LL-MANET-Routers". For IPv4, a well-known, link-local scope multicast address is required. The address for LL-MANET-Routers is 224.0.0.109. For IPv6, a well-known, link-local scope multicast address is required. The address for LL-MANET-Routers is FF02:0:0:0:0:0:0:6D. 6. IANA Considerations This document enumerates several common IANA allocations for use by one or more protocols that conform to [RFC5444]. Specifically, the following well-known numbers have been assigned: a UDP port (Section 3), an IP protocol number (Section 4), and a link-local multicast group address (Section 5). Action 1: IANA has made the following assignments in the "PORT NUMBERS" registry: sub-registry "WELL KNOWN PORT NUMBERS" Keyword Decimal Description References ------- ------- ----------- ---------- manet 269/udp MANET Protocols [RFC5498] Action 2: IANA has made the following assignments in the "PROTOCOL NUMBERS" registry: sub-registry "WELL KNOWN PORT NUMBERS" Keyword Decimal Description References ------- ------- ----------- ---------- manet 138 MANET Protocols [RFC5498] Chakeres Standards Track [Page 3]
RFC 5498 IANA Allocations for MANET Protocols March 2009 Action 3: IANA has made the following assignments in the "Internet Multicast Addresses" registry: sub-registry "224.0.0.0 - 224.0.0.255 (224.0.0/24) Local Network Control Block" 224.0.0.109 LL-MANET-Routers [RFC5498] Action 4: IANA has made the following assignments in the "INTERNET PROTOCOL VERSION 6 MULTICAST ADDRESSES" registry: sub-registry "Fixed Scope Multicast Addresses" sub-sub-registry "Link-Local Scope" FF02:0:0:0:0:0:0:6D LL-MANET-Routers [RFC5498] 7. Security Considerations This document specifies only well-known numbers for protocols that conform to [RFC5444], and it not does not specify the protocols that carry the information across the network. Each protocol using these well-known numbers may have its own set of security issues, but those issues are not affected by using the IANA allocations specified herein. The security issues associated with possibly operating multiple cooperating protocols using the same IANA assignments (e.g., UDP port) MUST be addressed in each protocol's specification. 8.
