A network administrator is troubleshooting an EIGRP problem on a router and needs to confirm the IP addresses of the devices with which the router has established adjacency. The retransmit interval and the queue counts for the adjacent routers also need to be checked. What command will display the required information?
The command that will display the required information is:
A. Router# show ip eigrp neighbors
EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary routing protocol that is used to route IP traffic within a network. In order to troubleshoot EIGRP, we need to check the IP addresses of the devices that the router has established adjacency with, as well as the retransmit interval and queue counts for those adjacent routers.
The "show ip eigrp neighbors" command will display the neighboring devices that have established adjacency with the router running EIGRP. This command will show the IP addresses of the neighboring devices, the interface on which the adjacency was established, the hold time, and the uptime of the adjacency. It will also show the retransmit interval and the queue counts for each adjacent router.
Therefore, option A is the correct answer. Option B ("show ip eigrp interfaces") will only display information about the interfaces on which EIGRP is enabled. Option C ("show ip eigrp adjacency") does not exist as a valid command in Cisco IOS. Option D ("show ip eigrp topology") will display the EIGRP topology table, which is not relevant to this particular troubleshooting scenario.
