Ospfv3Packet	class	Common OSPFv3 packet header - this header is present in every OSPFv3 packet

Fields

Name	Type	Description
type
reserved1	uint8_t	8 bits
options	Ospfv3Options	24 bits
interfaceMTU	uint16_t	16 bits

version
instanceID	int8_t
reserved	uint8_t	RFC 5340 A.3.1. The OSPF Packet Header: Checksum: OSPF uses the standard checksum calculation for IPv6 applications: The 16-bit one's complement of the one's complement sum of the entire contents of the packet, starting with the OSPF packet header, and prepending a "pseudo-header" of IPv6 header fields, as specified in Section 8.1 of [IPV6]. The "Upper-Layer Packet Length" in the pseudo-header is set to the value of the OSPF packet header's length field. The Next Header value used in the pseudo-header is 89. If the packet's length is not an integral number of 16-bit words, the packet is padded with a byte of zero before checksumming. Before computing the checksum, the checksum field in the OSPF packet header is set to 0.
