Configuring OSPF
26
The <name> parameter specifies the prefix list name. You use this name when applying the prefix
list to a neighbor.
The seq <seq-value> parameter is optional and specifies the IP prefix list’s sequence number. If
you do not specify a sequence number, the software numbers them in increments of 5, beginning
with prefix list entry 5. The software interprets the prefix list entries in numerical order, beginning
with the lowest sequence number.
The description <string> parameter is a text string describing the prefix list.
The deny | permit parameter specifies the action the software takes if a neighbor’s route is in this
prefix list.
The prefix-list matches only on this network unless you use the ge <ge-value> or le <le-value>
parameters. (See below.)
The <network-addr>/<mask-bits> parameter specifies the network number and the number of bits
in the network mask.
You can specify a range of prefix length for prefixes that are more specific than
<network-addr>/<mask-bits>.
• If you specify only ge <ge-value>, then the mask-length range is from <ge-value> to 32.
• If you specify only le <le-value>, then the mask-length range is from length to <le-value>.
• The <ge-value> or <le-value> you specify must meet the following condition.
length < ge-value <= le-value <= 32
If you do not specify ge <ge-value> or le <le-value>, the prefix list matches only on the exact
network prefix you specify with the <network-addr>/<mask-bits> parameter.
