Dell Force10 C150 Configuration Manual page 155

If you are creating a standard prefix list with only one or two filters, you can let FTOS assign a sequence
number based on the order in which the filters are configured. The FTOS assigns filters in multiples of
five.
To configure a filter without a specified sequence number, use these commands in the following sequence
starting in the CONFIGURATION mode:
Step Command Syntax
ip prefix-list
1 prefix-name
{ deny | permit }
2
] [ le
min-prefix-length
]
max-prefix-length
Figure 8-14 illustrates a prefix list in which the sequence numbers were assigned by the software. The
filters were assigned sequence numbers based on the order in which they were configured (for example,
the first filter was given the lowest sequence number). The
mode displays the two filters with the sequence numbers 5 and 10.
Figure 8-14. Prefix List
FTOS(conf-nprefixl)#permit 123.23.0.0 /16
FTOS(conf-nprefixl)#deny 133.24.56.0 /8

ip prefix-list awe
seq 5 permit 123.23.0.0/16
seq 10 deny 133.0.0.0/8
FTOS(conf-nprefixl)#
To delete a filter, enter the
number of the filter you want to delete; then use the
LIST mode.
To view all configured prefix lists, use either of the following commands in the EXEC mode:
