10.2.1 Before You Start

Before configuring the IP prefix list, familiarize yourself with the usage scenario, complete the
pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.

matches the destination address of a route.

10.2.2 Configuring an IPv4 Prefix List
An IP prefix list filters routes according to IP address prefixes. An IP address prefix is defined
by the IP address and mask length.
Context
Perform the following steps on the router to which the IP prefix list is applied:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ip ip-prefix ip-prefix-name [ index index-number ] { permit | deny } ip-address
mask-length [ match-network ] [ greater-equal greater-equal-value ] [ less-equal
less-equal-value ]
An IPv4 prefix list is configured.
match-network is used to filter routes to a specified IP address and can be configured only when
ipv4-address is 0.0.0.0. For example, the ip ip-prefix prefix1 permit 0.0.0.0 8 command filters
