Glean adjacency

When a router is connected to a subnet, the FIB table maintains a prefix for the subnet rather than for each individual host. This subnet prefix points to a glean adjacency. When a packet must be forwarded to a specific host, the adjacency database is gleaned for the specific prefix.

Output of show ip cef glean appears as follows:
