# RIP Virtual Router Settings

The Virtual Router RIP Settings page enables you to create and modify parameters for Routing Information Protocol (RIP) in a virtual router on your NetScreen device. The Virtual Router RIP Settings page contains a series of check boxes and information boxes that enable you to create a RIP instance. To create or edit a RIP instance, enter the necessary information, and then click OK to save your changes. Or click Apply to save your changes and continue the RIP configuration.

Protocol RIP: Select this check box to enable RIP in the virtual router.

Version: Select the RIP protocol version (version 1 or version 2) for this RIP instance.

Reject Default Route Learnt by RIP: Select this check box to reject a default route learned from another protocol.

Allow Neighbors From Different Subnets: Select this check box to allow RIP neighbors that are on the different subnets.

Advertising Default Route: Select this check box to advertise its default route.

metric: Enter a value that represents the desirability of the default route of the current RIP instance. This value is the metric of the route.

always: Select this check box to indicate you want the current RIP instance to always advertise its default route.

Metric for Redistributed Routes: Enter a value that represents the metric of routes imported into RIP from other protocols, such as OSPF or BGP.

Maximum Alternative Route: Enter a value for the maximum number of alternate routes kept in the RIP database for each network prefix. 0 means that no alternate routes are kept in the database.

Hold-down Timer: Enter the number of seconds that elapses before the virtual router updates the routing table when RIP detects a route with a high metric.

Retransmit Timer: Enter the interval, in number of seconds, at which triggered responses are retransmitted over a demand circuit. The Retry Count is the number of times a response is retransmitted before the demand circuit is placed into POLL state.

Poll Timer: Enter the interval, in number of seconds, at which triggered requests are sent over the demand circuit to check if the other end of the circuit has come up. The Retry Count is the number of times that the triggered requests are sent before the demand circuit is considered to be down.

Periodic Route Update Interval: Enter a value that indicates the number of seconds between updates of RIP routes to neighbors.

Route Invalidation Interval: Enter a value that indicates the number of seconds after a RIP neighbor stops advertising a route that the route is considered invalid.

Route Flushing Interval: Enter a value that indicates the number of seconds after a route is invalidated that it is removed.

Maximum Number Packets per Update Timer: Select this check box to set a maximum number of packets that can be received per update. Enter a value that indicates the maximum number of packets received per update.

Trusted Neighbors: Select this check box to specify allowable RIP neighbors. Enter the access list ID that defines RIP neighbors.

Maximum Neighbors: Enter a value that indicates the maximum number of RIP neighbors.

Incoming Route Map Filter: Enter the route map ID that defines routes to be learned by RIP.

Outgoing Route Map Filter: Enter the route map ID that defines routes to be advertised by RIP.
