Filtering by prefix list involves matching the prefixes of routes with those listed in the prefix list. When there is a match, the rule is used. The prefix lists can be used to filter out [[RIP]] routes, and are used if specified under <code>/routing rip interface</code>.


 
<table class="styled_table">
<tr>
<th width="40%">Property</th>
<th >Description</th>
</tr>
<tr>
<td><var>action</var> (accept | discard; Default: accept)</td>
<td> action to perform on route matching the rule</td>
</tr>
<tr>
<td><var>chain</var> (string; Default: "")</td>
<td> chain name to place this rule in. If a chain with the specified name does not exist it will be automatically created</td>
</tr>
<tr>
<td><var>invert-math</var> (yes | no; Default: no)</td>
<td> invert this match, i.e. apply the rule to routes that would fail to match it and vice versa</td>
</tr>
<tr>
<td><var>prefix</var> (IP prefix; Default: 0.0.0.0/0)</td>
<td> network prefix to match. If prefix-length is not set, only exact match is done. For example, 0.0.0.0/0 then matches only the default route and nothing else</td>
</tr>
<tr>
<td><var>prefix-length</var> (integer; Default: 0-32)</td>
<td> network prefix mask length to match. If prefix-length is set, for a route to match the prefix and prefix-length of a rule, the following should hold:
:* the network prefix of the route falls within the range of the prefix of the rule, (i.e.
::* the network mask of the route is greater of equal than the network mask of the prefix;
::* the network address of the route masked out by the network mask of the prefix is equal to the network address of the prefix;)
:* the length of the network mask of the route falls within the range of the prefix-length</td>
</tr>
<tr>
<td><var>set-metric</var> (integer; Default: )</td>
<td> Set metric</td>
