51 * P: This is the proxy Map-Reply bit. When set to 1, an ETR sends a
52 * Map-Register message requesting the Map-Server to proxy a Map-Reply. The
53 * Map-Server will send non-authoritative Map-Replies on behalf of the ETR.
54 * Details on this usage can be found in [RFC6833].

58 * M: This is the want-map-notify bit. When set to 1, an ETR is requesting a
59 * Map-Notify message to be returned in response to sending a Map-Register
60 * message. The Map-Notify message sent by a Map-Server is used to
61 * acknowledge receipt of a Map-Register message.

66 * Nonce: This 8-octet 'Nonce' field is set to 0 in Map-Register messages.
67 * Since the Map-Register message is authenticated, the 'Nonce' field is not
68 * currently used for any security function but may be in the future as part
69 * of an anti-replay solution.
74 * Key ID: This is a configured ID to find the configured Message
75 * Authentication Code (MAC) algorithm and key value used for the
76 * authentication function. See Section 14.4 for codepoint assignments.
81 * Authentication Data Length: This is the length in octets of the
82 * 'Authentication Data' field that follows this field. The length of the
83 * 'Authentication Data' field is dependent on the MAC algorithm used. The
84 * length field allows a device that doesn't know the MAC algorithm to
85 * correctly parse the packet. private short authenticationLength;
89 * Authentication Data: This is the message digest used from the output of
90 * the MAC algorithm. The entire Map-Register payload is authenticated with
91 * this field preset to 0. After the MAC is computed, it is placed in this
92 * field. Implementations of this specification MUST include support for
93 * HMAC-SHA-1-96 [RFC2404], and support for HMAC-SHA-256-128 [RFC4868] is

100 * above and occurs the number of times equal to Record Count.
