User Guidelines
This command without the seq keyword adds the new entry after the last entry of
the prefix list with the sequence number equals to the last number plus 5. For
example, if the last configured sequence number is 43, the new entry will have the
sequence number of 48. If the list is empty, the first prefix-list entry is assigned the
number 5 and subsequent prefix list entries increment by 5.
This command with the seq keyword puts the new entry into the place specified
by the parameter, if an entry with the number exists it is replaced by the new one.
This command without the seq keyword removes the prefix list.
The no version of this command with the seq keyword removes the specified
entry.
The sequence number of a prefix list entry determines the order of the entries in
the list. The router compares network addresses to the prefix list entries. The
router begins the comparison at the top of the prefix list, with the entry having the
lowest sequence number.
If multiple entries of a prefix list match a prefix, the entry with the lowest sequence
number is considered the real match. Once a match or deny occurs, the router
does not go through the rest of the prefix list. For efficiency, you might want to put
the most common permits or denies near the top of the list, using the seq-number
argument.
The show ipv6 prefix-list
IPv6 prefix lists are used to specify certain prefixes or a range of prefixes that
must be matched before a permit or deny statement can be applied. Two operand
keywords can be used to designate a range of prefix lengths to be matched. A
prefix length of less than, or equal to, a value is configured with the le keyword. A
argument. It is the lowest value of a range of the length (the
argument. It is the highest value of a range of the length (the
command displays the sequence numbers of entries.
