RIP 97

Table 97 Setting Additional Routing Metric

Operation	Command
Disable the additional routing metric of the	undo rip	metricin
route when the interface receives an RIP
packet
Set the additional routing metric of the route	ip metricout value
when the interface sends an RIP packet
Disable the additional routing metric of the	undo rip	metricout
route when the interface sends an RIP packet

By default, the additional routing metric added to the route when RIP sends the packet is 1. The additional routing metric when RIP receives the packet is 0.

Configuring Route Filtering

The router provides the route filtering function. You can configure the filter policy rules by specifying the ACL and ip-prefix for route redistribution and distribution. To import a route, the RIP packet of a specific router can also be received by designating a neighbor router.

Perform the following configurations in RIP view.

Table 98 Configuring RIP to Filter Routes

Operation	Command
Configure filtering the received routing	filter-policy gateway
information distributed by the specified	ip-prefix-name import
address
Cancel filtering the received routing	undo filter-policy gateway
information distributed by the specified	ip-prefix-name import
address

Configure filtering the received global routing information

Cancel filtering the received global routing information

filter-policy{ acl-number ip-prefixip-prefix-name } import

undo filter-policy { acl-number ip-prefix ip-prefix-name } import

By default, RIP does not filter received and distributed routing information.

Displaying and Debugging RIP

After configuring RIP, execute the display command in all views to display the RIP configuration, and to verify the effect of the configuration. Execute the debugging command in user view to debug the RIP module. Execute the reset command in RIP view to reset the system configuration parameters of RIP.
