RIP routes can be filtered by a distribute-list.
You can apply access lists to the interface with a
distribute-listcommand. access_list is the access list name. direct is in or out. If direct is in the access list is applied to input packets.
distribute-listcommand can be used to filter the RIP path.
distribute-listcan apply access-lists to a chosen interface. First, one should specify the access-list. Next, the name of the access-list is used in the distribute-list command. For example, in the following configuration eth0 will permit only the paths that match the route 10.0.0.0/8! router rip distribute-list private in eth0 ! access-list private permit 10 10.0.0.0/8 access-list private deny any !
distribute-list can be applied to both incoming and outgoing data.
