Here is an example of how to use the direct option. To display only the IP routes that go to devices directly attached to the Layer 3
switch, enter the following command.
device# show ip route direct
Start index: 1 B:BGP D:Connected R:RIP S:Static O:OSPF *:Candidate default
Destination NetMask Gateway Port Cost Type
10.157.22.0 255.255.255.0 0.0.0.0 1/4/11 1 D
Notice that the route displayed in this example has "D" in the Type field, indicating the route is to a directly connected device.
Here is an example of how to use the static option. To display only the static IP routes, enter the following command.
device# show ip route static
Start index: 1 B:BGP D:Connected R:RIP S:Static O:OSPF *:Candidate default
Destination NetMask Gateway Port Cost Type
10.144.33.11 255.255.255.0 10.157.22.12 1/1/1 2 S
Notice that the route displayed in this example has "S" in the Type field, indicating the route is static.
Here is an example of how to use the longer option. To display only the routes for a specified IP address and mask, enter a command
such as the following.
device# show ip route 10.159.0.0/16 longer
Starting index: 1 B:BGP D:Directly-Connected R:RIP S:Static O:OSPF
Destination NetMask Gateway Port Cost Type
52 10.159.38.0 255.255.255.0 10.95.6.101 1/1/1 1 S
53 10.159.39.0 255.255.255.0 10.95.6.101 1/1/1 1 S
54 10.159.40.0 255.255.255.0 10.95.6.101 1/1/1 1 S
55 10.159.41.0 255.255.255.0 10.95.6.101 1/1/1 1 S
56 10.159.42.0 255.255.255.0 10.95.6.101 1/1/1 1 S
57 10.159.43.0 255.255.255.0 10.95.6.101 1/1/1 1 S
58 10.159.44.0 255.255.255.0 10.95.6.101 1/1/1 1 S
59 10.159.45.0 255.255.255.0 10.95.6.101 1/1/1 1 S
60 10.159.46.0 255.255.255.0 10.95.6.101 1/1/1 1 S
This example shows all the routes for networks beginning with 10.159. The mask value and longer parameter specify the range of
network addresses to be displayed. In this example, all routes within the range 10.159.0.0 - 10.159.255.255 are listed.
The summary option displays a summary of the information in the IP route table. The following is an example of the output from this
command.
device# show ip route summary
IP Routing Table - 35 entries:
6 connected, 28 static, 0 RIP, 1 OSPF, 0 BGP, 0 ISIS, 0 MPLS
Number of prefixes:
/0: 1 /16: 27 /22: 1 /24: 5 /32: 1
Syntax: show ip route summary
In this example, the IP route table contains 35 entries. Of these entries, 6 are directly connected devices, 28 are static routes, and 1 route
was calculated through OSPF. One of the routes has a zero-bit mask (this is the default route), 27 have a 22-bit mask, 5 have a 24-bit
mask, and 1 has a 32-bit mask.
The following table lists the information displayed by the show ip route command.
TABLE 24 CLI display of IP route table
Field Description
Destination The destination network of the route.
NetMask The network mask of the destination address.
Gateway The next-hop router.
Port The port through which this router sends packets to reach the route's
destination.
