Prerequisites

Before configuring this task, you must determine IP-prefix list name, matching address range, and
extcommunity list sequence number.

Defining an IP-prefix list

Define an IPv4 prefix list
Identified by name, an IPv4 prefix list can comprise multiple items. Each item specifies a prefix range to
match and is identified by an index number.
An item with a smaller index number is matched first. If one item is matched, the IP prefix list is passed,
and the routing information will not go to the next item.
Follow these steps to define an IPv4 prefix list:
To do...
Enter system view
Define an IPv4 prefix list
NOTE:
If all the items are set to the deny mode, no routes can pass the IPv4 prefix list. You must define the permit
0.0.0.0 0 less-equal 32 item following multiple deny items to allow other IPv4 routing information to pass.
For example, the following configuration filters routes 10.1.0.0/16, 10.2.0.0/16, and 10.3.0.0/16, but
allows other routes to pass.
