Displaying the Routing Table

Viewing information about the routing table helps locate faults on the network.

Context

It is necessary to check the information in the routing table using display commands in order to locate routing problems. The display commands can be used in all views. Common commands for displaying routing information are listed as follows:

Procedure

To check brief information about activated routes in the IP routing table, run the display ip routing-table command.
To check detailed information about the IP routing table, run the display ip routing-table verbose command.
To check limits on the number of routes and prefixes, run the display ip routing-table limit [ all-vpn-instance | vpn-instance vpn-instance-name ] command.
To check the number of routes, run the display ip routing-table route-number command.
To check the route to the specified destination IP address, run the display ip routing-table ip-address [ mask | mask-length ] [ longer-match ] [ verbose ] command.
To check routes to the specified range of destination IP addresses, run the display ip routing-table ip-address1 { mask1 | mask-length1 } ip-address2 { mask2 | mask-length2 } [ verbose ] command.
To check the routes discovered by the specified protocol, run the display ip routing-table protocol { direct | ospf | isis | static | rip | bgp | unr } [ inactive | verbose ] command.
To check general information about the routing table, run the display ip routing-table statistics command.
To check brief information about the VPN routing table, run the display ip routing-table vpn-instance vpn-instance-name command.
To check detailed information about the VPN routing table, run the display ip routing-table vpn-instance vpn-instance-name verbose command.
To check detailed information about the route to the specified destination IP address in the VPN routing table, run the display ip routing-table vpn-instance vpn-instance-name ip-address [ mask | mask-length ] [ longer-match ] [ verbose ] command.
To check detailed information about the routes to the specified network segment in the VPN routing table, run the display ip routing-table vpn-instance vpn-instance-name ip-address1 { mask1 | mask-length1 } ip-address2 { mask2 | mask-length2 } [ verbose ] command.
To check brief information about activated routes in the IPv6 routing table, run the display ipv6 routing-table command.
To check detailed information about the IPv6 routing table, run the display ipv6 routing-table verbose command.
To check brief information about the IPv6 routing table, run the display ipv6 routing-table [ vpn-instance vpn-instance-name ] simple command.
To check limits on the number of IPv6 routes and prefixes, run the display ipv6 routing-table limit [ all-vpn-instance | vpn-instance vpn-instance-name ] command.
To check the number of IPv6 routes, run the display ipv6 routing-table route-number command.
To check the route to the specified destination IPv6 address, run the display ipv6 routing-table ipv6-address [ prefix-length ] [ longer-match ] [ verbose ] command.
To check routes to the specified range of destination IPv6 addresses, run the display ipv6 routing-table ipv6-address1 [ prefix-length1 ] ipv6-address2 prefix-length2 [ verbose ] command.
To check the IPv6 routes discovered by the specified protocol, run the display ipv6 routing-table protocol { bgp | direct | isis | ospfv3 | ripng | static | unr } [ inactive | verbose ] command.
