Explanation:
Open Shortest Path First (OSPF) is a routing protocol that uses link-state routing (LSR) algorithm. The OSPF protocol is used to advertise the availability of networks and dynamically calculate the shortest path between the source and the destination. OSPF packets are used to communicate routing information between OSPF routers.
The OSPF packet header comprises several fields that are used to convey information about the OSPF packet. These fields include:
a) Packet length: This field indicates the total length of the OSPF packet in bytes, including the OSPF packet header and the OSPF payload.
b) Router ID: This field contains the ID of the router that originated the OSPF packet, which is a 32-bit value that uniquely identifies the router.
c) Authentication type: This field specifies the type of authentication used by the OSPF packet. OSPF supports several authentication types, including null authentication, simple password authentication, and cryptographic authentication.
d) Maxage time: This field is not a field within an OSPF packet header. It is used to indicate the maximum age of an OSPF router in the LSDB (Link State Database) before it is considered invalid.
Therefore, option D is the correct answer as Maxage time is not a field within an OSPF packet header.
