The display commands can be used in all views. The reset commands are used in the user view.
Procedure
- Run the display ip routing-table command to check brief information about the active routes in the IPv4 routing table.
- Run the display ip routing-table verbose command to check detailed information about the IPv4 routing table.
- Run the display ip routing-table ip-address [ mask | mask-length ] [ longer-match ] [ verbose ] command to check detailed information about the routes with the specified destination address in the IPv4 routing table.
- Run the display ip routing-table ip-address1 { mask1 | mask-length1 } ip-address2 { mask2 | mask-length2 } [ verbose ] command to check detailed information about the routes within the specified destination address range in the IPv4 routing table.
- Run the display ip routing-table ip-prefix ip-prefix-name [ verbose ] command to check detailed information about the routes that match the specified IP prefix list in the IPv4 routing table.
- Run the display ip routing-table protocol protocol [ inactive | verbose ] command to check detailed information about the routes discovered by the specified routing protocol in the IPv4 routing table.
- Run the display ip routing-table statistics command to check route statistics in the IPv4 routing table.
- Run the display ipv6 routing-table command to check brief information about the active routes in the IPv6 routing table.
- Run the display ipv6 routing-table verbose command to check detailed information about the IPv6 routing table.
- Run the display ipv6 routing-table protocol protocol [ inactive | verbose ] command to check detailed information about the routes discovered by the specified routing protocol in the IPv6 routing table.
- Run the display ipv6 routing-table statistics command to check route statistics in the IPv6 routing table.
- To check brief information about the IPv6 routing table, run the display ipv6 routing-table [ vpn-instance vpn-instance-name ] simple command.
- Run the reset ip routing-table statistics protocol { all | protocol } command to clear route statistics in the IPv4 routing table.
- Run the reset ipv6 routing-table statistics protocol { all | protocol } command to clear route statistics in the IPv6 routing table.
