In the output in Example 5-15, the router ID is 192.168.1.65.
EIGRP routes that are found in the topology table but not in the routing table can indicate an issue
that requires help from Cisco Technical Assistance Center (TAC) to diagnose the problem.
Route ?¬?ltering enables routes to be ?¬?ltered from an EIGRP routing advertisement as they come in
from a neighbor or as they are sent out to a neighbor. These ?¬?lters can cause routes to be missing
from the routing table. The show ip protocols command shows whether any ?¬?lter lists are applied
to EIGRP.
