Layer 3 Routing Commands 1419
• list-name—The text name of the prefix list. Up to 32 characters.
• seq number—(Optional) The sequence number for this prefix list
statement. Prefix list statements are ordered from lowest sequence number
to highest and processed in that order. If a sequence number is not
specified, 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 value 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.
• network mask—Specifies the match criteria for routes being compared to
the prefix list statement. The network can be any valid IP prefix. The mask
is any IPv4 prefix in dotted-quad notation.
• ge length—(Optional) If this option is configured, a prefix is only
considered a match if its network mask length is greater than or equal to
this value. This value must be longer than the network length and less
than or equal to 32.
• le length—(Optional) If this option is configured, 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—Option to renumber the sequence numbers of the ip prefix
list statements with a given interval starting from a particular sequence
number.
Default Configuration
No prefix lists are 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.
