You can filter incoming and outgoing routes for a given IP interface using two Standard Access Lists - one for
input and one for output.
The standard Access List is a named, ordered list of pairs of IP prefix (IP address and IP mask length) and action.
The action can be
deny
or
permit
.
If an access list is defined, each route from the RIP message is checked against the list starting from the
first pair:
if it matches the first pair and the action is
permit
, the route is passed;
if the action is
deny
, the route is not passed. If the route does not match, the following pair is
considered.
If there is no pair that the route matches, the
deny
action is applied.
