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 Gateway of last resort is not set 1.0.0.0/32 is subnetted, 3 subnets R 1.1.1.1 [120/1] via 10.1.1.1, 00:00:15, FastEthernet0/0 R 1.3.3.3 [120/1] via 10.1.1.1, 00:00:15, FastEthernet0/0 R 1.2.2.2 [120/1] via 10.1.1.1, 00:00:15, FastEthernet0/0 2.0.0.0/32 is subnetted, 1 subnets C 2.2.2.2 is directly connected, Loopback0 33.0.0.0/32 is subnetted, 1 subnets O 33.33.33.33 [110/2] via 10.2.2.3, 00:01:08, FastEthernet1/0 3.0.0.0/32 is subnetted, 1 subnets O 3.3.3.3 [110/2] via 10.2.2.3, 00:01:08, FastEthernet1/0 113.0.0.0/32 is subnetted, 1 subnets O 113.113.113.113 [110/2] via 10.2.2.3, 00:01:08, FastEthernet1/0 111.0.0.0/32 is subnetted, 1 subnets D 111.111.111.111 [90/156160] via 10.1.1.1, 00:01:23, FastEthernet0/0 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 11.0.0.0/32 is subnetted, 1 subnets D 11.11.11.11 [90/156160] via 10.1.1.1, 00:01:23, FastEthernet0/0 133.133.0.0/32 is subnetted, 1 subnets O 133.133.133.133 [110/2] via 10.2.2.3, 00:01:09, FastEthernet1/0
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
