le length
(Optional) If this option is configured, then a prefix is only considered a
match if its network mask length is less than or equal to this value. This
value must be longer than the ge length and less than or equal to 32.
renumber renumber-interval
first-statement-number
(Optional) Provides the option to renumber the sequence numbers of
the IP prefix list statements with a given interval starting from a
particular sequence number. The valid range for renumber-interval is 1-
100, and the valid range for first-statement-number is 1-1000.
Default
Prefix lists are not configured by default. When neither the
ge
nor the
le
option
is configured, the
destination prefix must match the network/length exactly. If the
ge
option is configured without the
le
option, any prefix with a network mask greater than or equal to the
ge
value is considered a match.
Similarly, if the
le
option is configured without the ge option, a prefix with a network mask less than or
equal to the le value is considered a match.
