Layer 3 Routing Commands 1389
User Guidelines
A community list statement with no community values is considered a match
for all routes, regardless of their community membership. So the statement
ip community-list bullseye permit is a permit all statement.
A community number may be entered in either format, as a 32-bit integer or a
pair of 16-bit integers separated by a colon, regardless of whether the ip bgp-
community new-format command is active. Up to 16 communities, including
the well-known communities, can be listed in a single command. Up to 32
statements may be configured with a given community list name. Up to 128
unique community list names may be configured.
Example
console(config)#ip community-list test permit
ip prefix-list
To create a prefix list or add a prefix list entry, use the ip prefix-list command
in global configuration mode. To delete a prefix list or a statement in a prefix
list, use the no form of this command.
Syntax
ip prefix-list list-name {[seq number] { permit | deny } network mask
[ge length] [le length] | renumber renumber-interval first-statement-number
}
no ip prefix-list list-name [seq number] { permit | deny } network mask
[ge length] [le length]
• 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.
