By default, RIP does not filter outbound routes.
If a
protocol
is specified, RIP filters only the routes redistributed from the specified routing protocol.
Otherwise, RIP filters all routes to be advertised.
If
interface-type interface-number
is specified, RIP filters only the routes advertised by the specified
interface. Otherwise, RIP filters routes advertised by all RIP interfaces.
If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the
ACL should be configured with the
rule
[
rule-id
] {
deny
|
permit
}
ip source
sour-addr sour-wildcard
command to deny/permit a route with the specified destination, or with the
rule
[
rule-id
] {
deny
|
permit
}
ip source
sour-addr sour-wildcard
destination
dest-addr dest-wildcard
command to
deny/permit a route with the specified destination and mask. The
source
keyword specifies the
destination address of a route and the
destination
keyword specifies the subnet mask of the route
(the subnet mask must be valid; otherwise, the configuration is ineffective).
