Use this command to display information about IP routes.
| host | (Optional) Displays routes configured on the host stack. |
| address-or-prefix | (Optional) Specifies whether following is destination address or subnet prefix. |
| dest-address [prefix-mask] | (Optional) Converts the specified destination address and optional mask into a prefix and displays any routes that match the prefix. |
| prefix/prefix-length | (Optional) Displays any routes that match the specified prefix and prefix-length. |
| longer-prefixes | (Optional) Displays all routes that match the specified prefix and length. |
| connected | (Optional) Displays directly connected routes. |
| host-address | (Optional) Displays host interface addresses. |
| dynamic | (Optional) Displays dynamic routes learned via protocols. |
| ospf | (Optional) Displays routes configured for the OSPF routing protocol. For details on configuring OSPF, refer to the S-, K-, and 7100 Series Configuration Guide. |
| bgp | (Optional) Displays routes configured for the BGP routing protocol. For details on configuring BGP, refer to the S-, K-, and 7100 Series Configuration Guide (S-, 7100-Series). |
| isis | (Optional) Displays routes configured for the ISIS routing protocol. For details on configuring ISIS, refer to the S-, K-, and 7100 Series Configuration Guide. |
| rip | (Optional) Displays routes configured for the RIP routing protocol. For details on configuring RIP, refer to the S-, K-, and 7100 Series Configuration Guide. |
| static | (Optional) Displays static routes. |
| summary | (Optional) Displays a summary of the IP routing table. |
| topology <topology-name> | (Optional) Displays routes for the specified topology. |
All command modes.
Routes are managed by the RTM (Route Table Manager), and are contained in the RIB (Route Information Base). This database contains all the active static routes, all the RIP routes, and up to eight best routes to each network as determined by OSPF.
To display entries in an IPv4 multicast topology routing table, use the show ip route command with the topology option.
The RTM selects up to eight of the best routes to each network and installs these routes in the FIB (Forwarding Information Base). The routes in the FIB are distributed to every module for use by the router's ingress module as frames are received.
