A. Command Line Interface
A-8 November 2003 6300-A2-GB20-10
Bridge Commands
ip route create upstream eth1[:ifn] next-hop-ip
ip route delete upstream eth1[:ifn]
Minimum Access Level: Administrator
Command Mode: Config
Enters or deletes upstream IP routing table entries. When the DSL interface is
unnumbered, an IP routing table entry is automatically created, with the next hop router as
remote. To configure downstream routers, refer to the previous set of entries.
Example: Refer to Chapter 4, DSL Router Configuration Examples.
create – Creates an upstream IP route table entry.
delete – Deletes an upstream IP route table entry.
eth1, eth1:1, eth1:2, eth1:3, eth1:4 – Specifies the logical Ethernet interface (eth1 is the
same as eth1:1).
next-hop-ip – IP address of the next hop upstream router used to reach the remote
destination.
NOTE: When the DSL interface is numbered, the next hop router IP address must fall
into one of the service domain IP subnets configured for the DSL interface.
ip route purge
Minimum Access Level: Administrator
Command Mode: Config
Deletes all IP route table entries, including interface routes and those automatically added
by DHCP Server and DHCP Relay agent.
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.
Table A-5. IP Routing Commands (2 of 2)
Table A-6. Bridge Commands (1 of 2)
bridge { enable | disable }
Minimum Access Level: Administrator
Command Mode: Config
Enables or disables transparent bridging of traffic in the service domain. Bridging is only
supported when both the router and network are in VNET mode. Traffic in the
management domain is unaffected by this command; IP traffic is always enabled for
management traffic. Refer to the Show Commands on page A-24 to see the router’s
bridge configuration and filtering database.
enable – Bridging is activated in the service domain. All protocols, including IP, are
bridged unless IP routing is enabled. This is the default setting.
disable – No bridging can take place.
