Functional Notes

This command specifies a prefix to be matched. Option ally, it may specify a range of mask lengths. The

following rule must be followed: len < ge-value

le-value. A prefix list with no entries allows all routes. A

route that does not match any entries in a prefix list is dropp ed . As soon as a route is per mitted or denied,

there is no further processing of the rule in the prefix list. A route that is denied at the beginning entry of a

prefix list will not be allowed, even if it matches a permitting entry further down the list.
