Voyager Reference Guide 3337. To redistribute OSPF routes, enter the IP prefix in the NEW IP PREFIX TOREDISTRIBUTE edit box and the mask length in MASK LENGTH edit box;then click APPLY.Inbound Route FiltersDescriptionInbound route filters allow a network administrator to restrict or constrain theset of routes that a given routing protocol accepts. The filters allow anoperator to include or exclude ranges of prefixes from the routes that areaccepted into RIP, IGRP, OSPF and BGP. These filters are configured in thesame way as the filters for route redistribution.There are two possible actions an administrator can specify for each prefix.These actions are either to accept the address into the routing protocol (with aspecified rank) or to exclude the prefix.There are four different ways to specify the type of prefix matching thatshould be done for filter entries.1. Routes that exactly match the given prefix; that is, have the same networkportion and prefix length.2. Routes that match more specific prefixes but do not include the givenprefix. For example, if the filter is 10/8, then any network 10 route with aprefix length greater than 8 matches, but those with a prefix length of 8 donot match.3. Routes that match more specific prefixes and include the given prefix. Forexample, if the filter is 10/8, then any network 10 route with a prefixlength greater than or equal to 8 matches.4. Routes that match a given prefix with a prefix length between a givenrange of prefix lengths. For example, the filter could specify that it matchany route in network 10 with a prefix length between 8 and 16.
