+@section zebra Route Filtering
+Zebra supports @command{prefix-list} and @command{route-map} to match
+routes received from other quagga components.  The
+@command{permit}/@command{deny} facilities provided by these commands
+can be used to filter which routes zebra will install in the kernel.
+
+@deffn Command {ip protocol @var{protocol} route-map @var{routemap}} {}
+Apply a route-map filter to routes for the specified protocol. @var{protocol}
+can be @b{any} or one of
+@b{system},
+@b{kernel},
+@b{connected},
+@b{static},
+@b{rip},
+@b{ripng},
+@b{ospf},
+@b{ospf6},

+@deffn {Route Map} {set src @var{address}}
+Within a route-map, set the preferred source address for matching routes
+when installing in the kernel.
+@end deffn
+
+@example
+The following creates a prefix-list that matches all addresses, a route-map
+that sets the preferred source address, and applies the route-map to all
+@command{rip} routes.
+
+@group
+ip prefix-list ANY permit 0.0.0.0/0 le 32
+route-map RM1 permit 10
+     match ip address prefix-list ANY
+     set src 10.0.0.1

 Display whether the host's IP forwarding function is enabled or not.
 Almost any UNIX kernel can be configured with IP forwarding disabled.
