Notice that when the networks for the serial links from R3 to R1 and R3 to R2 are added
to the EIGRP configuration, DUAL sends a notification message to the console stating that
a neighbor relationship with another EIGRP router has been established.
Task 6: Verify EIGRP Operation
View neighbors.
Step 1.
On the R1 router, use the
show ip eigrp neighbors
command to view the neighbor table
and verify that EIGRP has established an adjacency with the R2 and R3 routers. You
should be able to see the IP address of each adjacent router and the interface that R1 uses
to reach that EIGRP neighbor.
R1#
show ip eigrp neighbors
IP-EIGRP neighbors for process 1

View the routing protocol information.
Step 2.
On the R1 router, use the
show ip protocols
command to view information about the routing
protocol operation. Notice that the information that was configured in Task 5, such as protocol,
process ID, and networks, is shown in the output. The IP addresses of the adjacent neighbors
are also shown:
