Introduction This specification enables multiple instances of (DYMO [I-D.ietf-manet-dymo]) to run independently on the same node over the same interface(s). This document specifies a message TLV structure named MANET_ID for [I-D.ietf-manet-packetbb]. This TLV is used by a (DYMO) process to identify its information. On reception of a routing protocol message, if the value of the MANET_ID TLV is different from the (DYMO) routing process's configured MANET ID value, then the message is discarded without processing. 2. Terminology The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. Additionally, this document uses terminology from [I-D.ietf-manet-packetbb]. In this document, we define the following terminology: Process A (DYMO) process is a running instantiation of the (DYMO) routing protocol. Instance A (DYMO) instance is a separate protocol instance complete with its own protocol data structures (e.g. routing table), protocol state machines, and protocol processes (e.g. route discovery). MANET ID The MANET ID enables multiple instances of a (DYMO) routing protocol to be run independently on the same node over the same interface(s). Received messages whose MANET ID value is not identical to the routing protocol instance's MANET ID value are discarded without processing. Process's MANET ID Value () The MANET ID value associated with a (DYMO) routing process is referred to as its . Message's MANET ID Value () The MANET ID value associated with a (DYMO) routing protocol message is carried in a MANET_ID TLV, and it is referred to as the message's . Chakeres Expires August 5, 2008 [Page 3] Internet-Draft MANET-ID February 2008 3. MANET_ID TLV The MANET_ID TLV is a message TLV. The MANET_ID TLV is a single value TLV as defined in [I-D.ietf-manet-packetbb]. 4. (DYMO) Protocol Operation This section describes specific (DYMO) routing protocol behavior based on and . NOTE: The placement of the protocol operation text within this document serves as a temporary location for discussion. The protocol operation text here will be shifted into the protocol specifications of protocols that wish to use the MANET_ID TLV in the future. 4.1. (DYMO) Configuration A (DYMO) routing protocol instance must be administratively configured to only process messages with a specific MANET_ID value, . 4.2. Message Reception When a message is received without an MANET_ID TLV, the message's MANET_ID value () is assumed to be zero (0). When a message is received with more than one MANET_ID TLV, it is invalid and MUST NOT be processed. When a message is received with one MANET_ID TLV, is contained. If is identical to , then the message is processed normally. Otherwise, the message MUST NOT be not processed. 4.3. Sending Control Messages When a (DYMO) process with a configured sends routing protocol control messages, the information MUST be identified by tagging it with an MANET_ID TLV containing . If the (DYMO) process does not have a configured , then it SHOULD NOT include an MANET_ID TLV. If an MANET_ID TLV is included the value MUST be set to zero (0).
