Question: 1 / 400

What protocol number is assigned to EIGRP?

78

88

The correct answer, 88, corresponds to the protocol number assigned to Enhanced Interior Gateway Routing Protocol (EIGRP). This value is crucial because it allows routers to identify the EIGRP packets when exchanging routing information. Protocol numbers are essential components in the IP header, as they indicate which protocol is being encapsulated in the packet. The assignment of protocol numbers is managed by the Internet Assigned Numbers Authority (IANA), and in the case of EIGRP, it has been standardized to ensure consistent identification across different network devices and platforms. Understanding this protocol number helps network engineers configure and troubleshoot EIGRP operations effectively, ensuring better performance in routing decisions within an enterprise network.
