166 CHAPTER 6: USING ROUTING PROTOCOL COMMANDS
transmits it with the specified cost value. This command can greatly enhance the
RIP capability of obtaining routes, thus increases the RIP performance.
If the cost
value
is not specified, routes will be imported according to the
default cost ranging from 1 to 16. If the imported route cost value is 16, then
RIP continues to announce this cost to other routers running RIP, and marks this
route with HOLDDOWN. However, this router can still forward packets until the
Garbage Collection timer times out (defaults to 120 seconds).
Related commands: default cost.
Example
To import a static route with a cost of 4, enter the following:
<SW5500>system-view
System View: return to User View with Ctrl+Z.
[SW5500]rip
[SW5500-rip]import-route static cost 4
To set the default cost, and then import an OSPF route with this default cost, enter
the following two commands:
[SW5500-rip]default cost 3
[SW5500-rip]import-route ospf

Parameter
network_address
Enter the IP network address of an interface.
Description
Use the network command to enable Routing Information Protocol (RIP) on the
interface of a specified network segment connected to the router.
Use the undo network command to disable RIP on the interface. By default, RIP is
disabled on an interface.
After you have enabled RIP, you must also enable RIP for a specified interface using
this command. RIP only operates on the interface of specified network segments.
The undo network command is similar to the undo rip work command in the
VLAN Interface View, in that an interface using either command will result in the
interface not receiving/transmitting RIP routes. However, if you use
undo rip
work
, other interfaces will still forward the routes of the interfaces set to undo rip
work
. If you use undo network, other interfaces will not forward the routes of
interfaces set to
undo network.
