When a route-policy isused to filter routing information, if a route fails to pass the match test against anynode, the route information will not pass the filtering of the route-policy. When all thenodes in the route-policy are in the deny mode, no routing information will pass thefiltering of the route-policy.At least one item in an ip-prefix list should be in permit mode. The items in denymode can be defined first to rapidly filter out the routing information not meeting theconditions. However, if all the items are in the deny mode, no route will pass thefiltering of the ip-prefix list. Therefore, you need to define a permit 0.0.0.0 0greater-equal 0 less-equal 32 item following multiple deny mode items to permit allother routes to pass through (if less-equal 32 is not specified, only the default routewill be matched).
