Layer 3 Routing Commands 1422
• seq number—(Optional) The sequence number for this prefix list
statement. Prefix list statements are ordered from lowest sequence number
to highest and applied in that order. If you do not specify a sequence
number, the system automatically selects a sequence number five larger
than the last sequence number in the list. Two statements may not be
configured with the same sequence number. The sequence number ranges
from 1 – 4,294,967,294.
• permit—Permit routes whose destination prefix matches the statement.
• deny—Deny routes whose destination prefix matches the statement.
• ipv6-prefix—The IPv6 network assigned to the specified prefix list. This
argument must be in the form documented in RFC 2373 where the
address is specified in hexadecimal using 16-bit values between colons.
• prefix-length—The length of the IPv6 prefix given as part of the ipv6-
prefix. Required if a prefix is specified. A decimal value that indicates how
many of the high-order contiguous bits of the address comprise the prefix
(the network portion of the address) in /length format. A slash mark must
precede the decimal value in /length format.
• ge length—(Optional) Specifies a prefix length greater than or equal to the
ipv6-prefix /prefix-length arguments. It is the lowest value of a range of the
length (the “from” portion of the length range).
• le length—(Optional) Specifies a prefix length less than or equal to the
ipv6-prefix /prefix-length arguments. It is the highest value of a range of
the length (the “to” portion of the length range).
• description text—A description of the prefix list that can be up to 80
characters in length.
• renumber-interval—Option to renumber the sequence numbers of the
IPv6 prefix list statements with a given interval. The sequence is
renumbered with the statements separated by the interval value. The
renumber value ranges from 1 – 4,294,967,294.
• first-statement-number—Option to renumber the sequence numbers of
the IPv6 prefix list statements with a given interval starting from the
specified sequence number. The sequence is renumbered with the
statements separated by the interval value beginning with the first entry
with a sequence number greater than or equal to the specified value. The
sequence number ranges from 1 – 4,294,967,294.
