verbose: Displays detailed routing table information, including that for inactive routes. With this keyword absent, the command displays only brief information about active routes. Show |: Filters command output by specifying a regular expression. For more information about regular expressions, see the Fundamentals Configuration Guide. begin: Displays the first line that matches the specified regular expression and all lines that follow. exclude: Displays all lines that do not match the specified regular expression. include: Displays all lines that match the specified regular expression. regular-expression: Specifies a regular expression, which is a case sensitive string of 1 to 256 characters. DescriptionUse the display ip routing-table command to display brief information about active routes in the routing table. This command displays brief information about a routing table, with a routing entry contained in one line. The information displayed includes destination IP address/mask length, protocol, priority, cost, next hop and outbound interface. This command displays only the optimal routes in use. Use the display ip routing-table verbose command to display detailed information about all routes in the routing table. This command displays detailed information about all active and inactive routes, including the statistics of the entire routing table and information for each route. Examples# Display brief information about active routes in the routing table. display ip routing-table

Adv This route can be advertised. Delete This route is deleted. Gateway This is an indirect route. Holddown Number of holddown routes. Int The route was discovered by an Interior Gateway Protocol (IGP). NoAdv The route is not advertised when the router advertises routes based on policies. NotInstall Among routes to a destination, the route with the highest priority is installed into the core routing table and advertised. A NotInstall route cannot be installed into the core routing table but can be advertised. Reject The packets matching a Reject route will be dropped. Besides, the router sends ICMP unreachable messages to the sources of the dropped packets. The Reject routes are usually used for network testing. Static A static route is not lost when you perform the save operation and then restart the router. Routes configured manually are marked as static. Unicast Unicast routes Inactive Inactive routes Invalid Invalid routes WaitQ The route is the WaitQ during route recursion. TunE Tunnel GotQ The route is in the GotQ during route recursion. Age Time for which the route has been in the routing table, in the sequence of hour, minute, and second from left to right. Which command is used to see the routing table?Use the show ip route EXEC command to display the current state of the routing table.
Which command allows you to see all routes on a router?The netstat -r command displays the current routing information contained in the routing tables.
What is command to show the routing table on a Cisco router?On a Cisco router, the show ip route command is used to display the IPv4 routing table of a router.
