deletion and re-addition of all statements that should be later in the list than the newly
added statement.
types on an individual router. Names can be duplicated on different routers.
items that can be matched with a numbered standard IP access list are identical to the items that
can be matched with a named standard IP access list. Likewise, the items are identical with both
numbered and named extended IP access lists.
is that named access lists use a global command, which moves the user into a named IP access
list submode, under which the matching and permit/deny logic is configured. The other key
difference is that when a named matching statement is deleted, only that one statement is
deleted. With numbered lists, the deletion of any statement in the list deletes all the statements
in the list. (This feature will be demonstrated in more detail in an upcoming example.)
among all named access lists of all types in this router. Also, note that because the named list
does not imply standard or extended by the value of the number of the list, the command
explicitly states the type of access list. Also, the . . . represents all the matching parameters,
which are identical in meaning and syntax when comparing the respective numbered and named
IP access lists. Also note that the same command is used to enable the list on an interface for
both numbered and named lists.
