add ip prefixlist

Syntax ADD IP PREFIXList=name ENTry=1..65535

[ACTion={MATch|NOMatch}] [MASklength=range]

[PREfix=ipadd]

Description This command adds a numbered entry to a prefix list. If the prefix list does not

already exist, this command first creates it. You can create up to 400 prefix lists,

with up to 1000 entries in each list.

Parameter Description

PREFIXList A name to identify the prefix list. A string 1 to 15 characters long. Valid

characters are uppercase letters (A-Z), lowercase letters (a-z), digits

(0-9) and the underscore character (“_”). If name contains spaces, it

must be in double quotes.

Default: no default

ENTry An integer to specify the position of the new entry in the prefix list.

When the router or switch uses a prefix list, it checks the entries in

order, starting with the lowest, until it finds a match. Therefore, give

more specific entries lower numbers than general entries. If you leave

gaps between entry numbers, you can add future entries between

existing entries.

Each prefix list has an implicit final entry that matches all addresses,

with an action of nomatch.

Default: no default

ACTion Whether matching prefixes are included or excluded by the process

that is using the prefix list.

You can use multiple entries in a prefix list with actions of match and

nomatch to build up a list of prefixes. Prefixes with action=match are

included in the list. Then to use this list of prefixes, create a route map

that matches it and apply the route map in a route filtering process.

The route map also has an action parameter, which determines

whether the filtering process includes or excludes the prefixes in the

list.

Default: match

MATch The prefix list includes the prefix.

NOMatch The prefix list excludes the prefix.
