568 Configuring Routing• Source — Select the type of source route to configure for redistribution by RIP. Possible values are:– Static– Connected– OSPF• Metric — Sets the metric value to be used as the metric of redistributed routes. This field displays themetric if the source was pre-configured and can be modified. The valid values are 1 to 15.• Distribute List — Select the Access List that filters the routes to be redistributed by the destinationprotocol. Only permitted routes are redistributed.The drop-down menu lists the ACLs configured through the pages under Switching→NetworkSecurity→Access Control Lists→IP Access Control Lists. When used for route filtering, the onlyfields in an access list that get used are:– Source IP Address and netmask– Destination IP Address and netmask– Action (Permit or Deny)All other fields (source and destination port, precedence, tos, etc.) are ignored.The source IP address is compared to the destination IP address of the route. The source IP netmask inthe access list rule is treated as a wildcard mask, indicating which bits in the source IP address mustmatch the destination address of the route.NOTE: A 1 in the mask indicates a Don’t Care in the corresponding address bit.When an access list rule includes a destination IP address and netmask (an extended access list), thedestination IP address is compared to the network mask of the destination of the route. Thedestination netmask in the access list serves as a wildcard mask, indicating which bits in the route’sdestination mask are significant for the filtering operation.• Redistribute — Enables or disables the redistribution for the selected source protocol. This field has tobe enabled in order to be able to configure any of the route redistribution attributes.Creating a Configured Source1. Open the RIP Route Redistribution Configuration page.2.
