Show IP Route Connected Command on CISCO Router/Switch

Command

Show IP Route Connected

Use

Allows you to see just the directly connected routes installed in the routing table.

Syntax

Router#show ip route ospf

Example

Here’s an example of the show ip route connected command. First, here’s the entire routing table of R2, outputted from the show ip route command.

R2(config-if)#do sh ip route
Codes: C – connected, S – static, R – RIP, M – mobile, B – BGP
D – EIGRP, EX – EIGRP external, O – OSPF, IA – OSPF inter area
N1 – OSPF NSSA external type 1, N2 – OSPF NSSA external type 2
E1 – OSPF external type 1, E2 – OSPF external type 2
i – IS-IS, su – IS-IS summary, L1 – IS-IS level-1, L2 – IS-IS level-2
ia – IS-IS inter area, * – candidate default, U – per-user static route
o – ODR, P – periodic downloaded static route

Next, here’s the output from using the show ip route connected command, which filters the output to just the directly connected routes in the routing table.

R2(config)#do show ip route connected
2.0.0.0/32 is subnetted, 1 subnets
C 2.2.2.2 is directly connected, Loopback0
10.0.0.0/24 is subnetted, 2 subnets
C 10.2.2.0 is directly connected, FastEthernet1/0
C 10.1.1.0 is directly connected, FastEthernet0/0
