Command Line Interface
IP Routing Table

delete {e0[/ifn ] | d0[/ifn ] }
Deletes any of the assignments that are configured for the IP address or interface. Only
the specific Ethernet or DSL interface number needs to be specified.
An interface address and mask cannot be deleted while there is a static route (upstream
or downstream) that uses it. First, delete the IP route with the ip route delete
command (see IP Routing Table).
Minimum access level: Administrator/Config
e0, e0/1, e0/2, e0/3, e0/4 – Ethernet interface. e0 is the same as e0/1.
d0, d0/1, d0/2, d0/3, d0/4 – DSL interface. d0 is the same as d0/1. Only d0 or d0/1 are
acceptable inputs for an unnumbered interface.
Example: delete e0/4
ip route create dest-ip dest-mask {next-hop-ip | remote }
ip route delete dest-ip dest-mask
Configures the downstream static routes. Downstream routes cannot be created unless
at least one Ethernet interface has been configured.
create – Create an IP route table entry.
delete – Delete an 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 address and 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 must be
entered manually using ip route create or the 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.
dest-mask – IP 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 nonzero next-hop-ip address must be within the address range of an Ethernet
interface.
remote – Indicates that the device specified by the destination ip and destination 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 been configured.
