The following sample output shows the direct IP prefix when the next hop Gigabit Ethernet interface 3/0
is specified:
Router# show ip cef adjacency GigabitEthernet 3/0 172.20.26.29
Prefix Next Hop Interface

Cisco 10000 Series Routers Examples Only
The show ip cef adjacency command shows all prefixes resolved through a regular next-hop adjacency
or through the usage of a special adjacency type keyword such as discard, drop, glean, null, or punt.
The following is sample output from the show ip cef adjacency command when the glean keyword is
specified:
Router# show ip cef adjacency glean

10.17.250.252/32 10.2.61.1 GigabitEthernet1/0/0
The following is sample output from the show ip cef adjacency drop command with the detail keyword
specified:
Router# show ip cef adjacency drop detail
