When troubleshooting an EIGRP problem, you notice that two directly connected EIGRP routers are not forming an EIGRP relationship. A ping shows that the two routers can talk to each other. What is the next item that you should check?
A. Verify that the EIGRP hello and hold timers match.
B. Verify that EIGRP broadcast packets are not being.
C. Verify that EIGRP stub is configured on both routers.
D. Verify that EIGRP is enabled for the appropriate networks.
OSPF requires that the timers match; EIGRP does not. Also, the stub concept is a local feature to a router and also does not have to match. EIGRP sends to a multicast or unicast, not broadcast. We need to verify that the interfaces interconnecting the two routers are part of the EIGRP process. Use the show ip eigrp interface command to see which interfaces are part of the process.
