id	int
mutable	bool
complete	bool
correct	bool
properlyRepresented	bool
chunkLength	b
rawBin	string[]
rawHex	string[]
regionTags	SharingRegionTagSet::TagBaseRegionTag[]
version	short
type	PimPacketType
reserved	short	8 bits
checksum	uint16_t	The checksum is a standard IP checksum, i.e., the 16-bit one’s complement of the one’s complement sum of the entire PIM message, excluding the “Multicast data packet” section of the Register message. For computing the checksum, the checksum field is zeroed. If the packet’s length is not an integral number of 16-bit words, the packet is padded with a trailing byte of zero before performing the checksum. For IPv6, the checksum also includes the IPv6 “pseudo-header”, as specified in RFC 2460, Section 8.1 [5]. This “pseudo-header” is prepended to the PIM header for the purposes of calculating the checksum. The “Upper-Layer Packet Length” in the pseudo- header is set to the length of the PIM message, except in Register messages where it is set to the length of the PIM register header (8). The Next Header value used in the pseudo- header is 103.
