IP Routing Commands
Table A-5. IP Routing Commands (1 of 2)
ip route create dest-ip dest-mask {next-hop-ip | remote}
ip route delete dest-ip dest-mask
Minimum Access Level: Administrator
Command Mode: Config
Configures the downstream static routes. Downstream routes cannot be created unless at
least one Ethernet interface has been configured. To configure upstream routers, refer to
the next set of entries.
Example: Refer to Chapter 4, DSL Router Configuration Examples.
create – Create a downstream IP route table entry. To configure a downstream default
gateway, enter a destination IP address and a subnet mask of 0.0.0.0. A maximum of
32 static routes can be created.
delete – Delete a downstream IP route table entry. This will delete an IP route placed in
the table by the DHCP server, the DHCP relay, or manually entered static entries.
NOTE: An interface route is created automatically when an IP address and subnet
mask are assigned to an Ethernet interface with the ifn address command. The
Ethernet interface route can be deleted with the ip route purge or the ip route
delete command. Once deleted, the interface route can be entered manually using
ip route create or a new ifn address command.
dest-ip – IP address of the destination. The destination IP address must be within the
address range of a configured Ethernet interface or the next-hop-ip address must be
provided.
dest-mask – Subnet mask for the destination IP address.
next-hop-ip – IP address of the next hop downstream router used to reach the
destination. A next hop with an IP address of 0.0.0.0 specifies a directly reachable client.
A non-zero next-hop-ip address must be within the address range of an Ethernet
interface.
remote – Indicates that the device specified by the destination IP address and subnet
mask is logically within a local subnet route but is not on the physical Ethernet and resides
upstream from the DSL router. A remote route cannot be created unless at least one DSL
interface has previously been configured.
