Configure RIP on Interfaces
When you enable RIP globally on the system, interfaces meeting certain conditions start receiving RIP
routes.
By default, interfaces that you enable and configure with an IP address in the same subnet as the RIP
network address receive RIPv1 and RIPv2 routes and send RIPv1 routes.
Assign IP addresses to interfaces that are part of the same subnet as the RIP network identified in the
network
command syntax.
Controlling RIP Routing Updates
By default, RIP broadcasts routing information out all enabled interfaces, but you can configure RIP to
send or to block RIP routing information, either from a specific IP address or a specific interface.
To control which devices or interfaces receive routing updates, configure a direct update to one router
and configure interfaces to block RIP updates from other sources.
To control the source of RIP route information, use the following commands.
• Define a specific router to exchange RIP information between it and the Dell Networking system.
ROUTER RIP mode
neighbor ip-address
You can use this command multiple times to exchange RIP information with as many RIP networks as
you want.
• Disable a specific interface from sending or receiving RIP routing information.
ROUTER RIP mode
passive-interface interface
Assigning a Prefix List to RIP Routes
Another method of controlling RIP (or any routing protocol) routing information is to filter the
information through a prefix list. A prefix list is applied to incoming or outgoing routes.
Those routes must meet the conditions of the prefix list; if not, Dell Networking OS drops the route. Prefix
lists are globally applied on all interfaces running RIP. Configure the prefix list in PREFIX LIST mode prior
to assigning it to the RIP process.
For configuration information about prefix lists, refer to
Access Control Lists (ACLs) .
To apply prefix lists to incoming or outgoing RIP routes, use the following commands.
• Assign a configured prefix list to all incoming RIP routes.
ROUTER RIP mode
distribute-list prefix-list-name in
• Assign a configured prefix list to all outgoing RIP routes.
ROUTER RIP mode
distribute-list prefix-list-name out
To view the current RIP configuration, use the
show running-config
command in EXEC mode or the
show config
command in ROUTER RIP mode.
