- * PIMv2 uses encoded address representations.
- *
- * The last PIM-SM I-D before RFC2117 was published specified the

- * specified no encoding for unicast addresses with the unicast
- * address length specified in the header. Therefore, we have to
- * guess which encoding is being used (Cisco's PIMv2 implementation
- * uses the non-RFC encoding). RFC2117 turns a previously "Reserved"
- * field into a 'unicast-address-length-in-bytes' field. We guess
- * that it's the draft encoding if this reserved field is zero.
- *
- * RFC2362 goes back to the encoded format, and calls the addr length
- * field "reserved" again.
- *
- * The first byte is the address family, from:
- *
- * 0 Reserved
- * 1 IP (IP version 4)
- * 2 IP6 (IP version 6)
- * 3 NSAP
- * 4 HDLC (8-bit multidrop)
- * 5 BBN 1822
- * 6 802 (includes all 802 media plus Ethernet "canonical format")
- * 7 E.163
- * 8 E.164 (SMDS, Frame Relay, ATM)
- * 9 F.69 (Telex)
- * 10 X.121 (X.25, Frame Relay)
- * 11 IPX
- * 12 Appletalk
- * 13 Decnet IV
- * 14 Banyan Vines
- * 15 E.164 with NSAP format subaddress
- *
- * In addition, the second byte is an "Encoding". 0 is the default
- * encoding for the address family, and no other encodings are currently
- * specified.
