Controlling RIP Routing Updates
By default, RIP broadcasts routing information out all enabled interfaces, but you can congure RIP to send or to block RIP routing
information, either from a specic IP address or a specic interface.
To control which devices or interfaces receive routing updates, congure a direct update to one router and congure interfaces to
block RIP updates from other sources.
To control the source of RIP route information, use the following commands.
• Dene a specic 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 specic interface from sending or receiving RIP routing information.
ROUTER RIP mode
passive-interface interface
Adding RIP Routes from Other Instances
In addition to ltering routes, you can add routes from other routing instances or protocols to the RIP process.
With the redistribute command, you can include open shortest path rst (OSPF), static, or directly connected routes in the
RIP process.
To add routes from other routing instances or protocols, use the following commands.
• Include directly connected or user-congured (static) routes in RIP.
ROUTER RIP mode
redistribute {connected | static} [metric metric-value] [route-map map-name]
– metric-value: the range is from 0 to 16.
– map-name: the name of a congured route map.
• Include specic OSPF routes in RIP.
ROUTER RIP mode
redistribute ospf process-id [match external {1 | 2} | match internal] [metric value]
[route-map map-name]
Congure the following parameters:
– process-id: the range is from 1 to 65535.
– metric: the range is from 0 to 16.
– map-name: the name of a congured route map.
To view the current RIP conguration, use the show running-config command in EXEC mode or the show config
command in ROUTER RIP mode.
Assigning a Prex List to RIP Routes
Another method of controlling RIP (or any routing protocol) routing information is to lter the information through a prex list. A
prex list is applied to incoming or outgoing routes.
Those routes must meet the conditions of the prex list; if not, the system drops the route. Prex lists are globally applied on all
interfaces running RIP. Congure the prex list in PREFIX LIST mode prior to assigning it to the RIP process.
For conguration information about prex lists, refer to Access Control Lists (ACLs).
To apply prex lists to incoming or outgoing RIP routes, use the following commands.
