When a route is removed from the routing table, it is flagged as unusable by the receiving routers after seconds, and removed from their tables after an additional seconds. Advanced remote support tools are used to fix issues on any of your devices. The service includes support for the following:. Thank You Thank you for taking the time to respond.

Unless you have multiple routers you need to distribute routes to there really isn't any reason to run it. All it will do is put extra traffic on the wire and eat up a few cpu cycles on your router. The con to using it is that it will flood your network with updates periodically. If you only have a single router it is unnecessary.

Is there a benefit to enabling router RIP on my home router? Ask Question. Asked 11 years, 11 months ago. Active 3 years, 5 months ago. The auto-summary form of the command enables advertisement of the summarized routes. When used with the no form of the command, auto-summary disables the advertisement of the summarized routes. Delete all protocol-specific information from the global and interface context. NOTE: Deleting all protocol-specific information from the global and interface context sets all protocol parameters to default values.
By default, the switch interface increases the cost of an RIP route that is learned on the interface. The switch increases the cost by adding one to the route's metric before storing the route.
Use this metric only if you do not want the route to be used. In fact, you can prevent the switch from using a specific interface for routes learned though that interface by setting its metric to These commands configure vlan-1 to add 5 to the cost of each route learned on the interface. Configure redistribution filters to permit or deny redistribution for a route based on the destination network address or interface.
Route redistribution imports and translates different protocol routes into a specified protocol type. On the switches covered in this guide, redistribution is supported for static and directly connected routes. Redistribution of any other routing protocol into RIP is not currently supported. When you configure redistribution for RIP, you can specify that static or connected routes are imported into RIP routes.
To configure for redistribution, define the redistribution tables with "restrict" redistribution filters. NOTE: Do not enable redistribution until you have configured the redistribution filters.
Otherwise, the network might become overloaded with routes that you did not intend to redistribute. To configure the switch to filter out redistribution of static or connected routes on network The default configuration permits redistribution for all default connected routes only.
The default metric is a global parameter that specifies the cost applied to all RIP routes by default. The default value is 1. You can assign a cost from 1 to To assign a default metric of 4 to all routes imported into RIP, enter the following commands:. The default is 1. The basic form of the redistribute command redistributes all routes of the selected type. For finer control over route selection and modification of route properties, you can specify the route-map parameter and the name of a route map.
The no form of the command disables redistribution for the specified route type. Entering the command without the no option will re-enable Poison reverse. Split horizon - the routing switch does not advertise a route on the same interface as the one on which the routing switch learned the route.
This is the default. These loop prevention methods are configurable on an individual VLAN interface basis. Poison reverse is enabled by default. Disabling Poison reverse causes the routing switch to revert to Split horizon. Poison reverse is an extension of Split horizon. To disable Poison reverse on an interface, and thereby enable Split horizon, enter the following:. To display general RIP information, enter show ip rip at any context level.
The resulting display will appear similar to the following:. The following fields are displayed:. Status of the RIP protocol on the router. Status of auto-summary for all interfaces running RIP. If auto-summary is enabled, subnets will be summarized to a class network when advertising outside of the given network. Sets the default metric for imported routes. This is the metric that will be advertised with the imported route to other RIP peers.
