42gateway ip-prefix-name: References an IP prefix list to filter routes from the gateway. ip-prefix-name is astring of 1 to 19 characters.interface-type interface-number: Specifies an interface by its interface type and interface number.DescriptionUse the filter-policy import command to configure RIP to filter the incoming routes.Use the undo filter-policy import command to restore the default.By default, RIP does not filter incoming routes.NOTE:If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the ACLshould be configured with the rule [rule-id ] { deny | permit } ip sourcesour-addr sour-wildcardcommand to deny/permit a route with the specified destination, or with the rule [rule-id ] { deny |permit } ip sourcesour-addr sour-wildcard destinationdest-addr dest-wildcard command todeny/permit a route with the specified destination and mask. The source keyword specifies the destinationaddress of a route and the destination keyword specifies the subnet mask of the route (the subnet maskmust be valid; otherwise, the configuration is ineffective).Related commands: ip ip-prefix; acl (ACL and QoS Command Reference).Examples# Reference ACL 2000 to filter incoming routes. system-view[Sysname] acl number 2000[Sysname-acl-basic-2000] rule deny source 192.168.10.0 0.0.0.255[Sysname-acl-basic-2000] quit[Sysname] rip 1[Sysname-rip-1] filter-policy 2000 import# Reference IP prefix list abc on Vlan-interface 11 to filter all received RIP routes.[Sysname-rip-1] filter-policy ip-prefix abc import Vlan-interface 11# Configure ACL 3000 to permit only route 113.0.0.0/16 to pass, and reference ACL 3000 to filterincoming routes. system-view[Sysname] acl number 3000[Sysname-acl-adv-3000] rule 10 permit ip source 113.0.0.0 0 destination 255.255.0.0 0[Sysname-acl-adv-3000] rule 100 deny ip[Sysname-acl-adv-3000] quit[Sysname] rip 1[Sysname-rip-1] filter-policy 3000 importhost-routeSyntaxhost-routeundo host-routeViewRIP view
