Usage Guidelines

Usage Scenario

An IPv4 prefix list is used to filter IPv4 addresses. To achieve the following purposes, run the display ip ip-prefix command:

View detailed configuration of a configured IPv4 prefix list.
Check whether an IPv4 prefix list is deleted after running the undo ip ip-prefix command.
View the number of routes that do or do not match the route-policy in an IPv4 prefix list.

Precautions

The display ip ip-prefix command:

Displays the configuration of a specified IPv4 prefix list if the name of the IPv4 prefix list is specified.
Displays the configuration of all IPv4 prefix lists if no IPv4 prefix list name is specified.
Does not display information if no IPv4 prefix list exists in the system or the queried IPv4 prefix list does not exist.

Before collecting the number of routes that do or do not match the route-policy in an IPv4 prefix list within a certain period, run the reset ip ip-prefix command to clear existing statistics.

If The specified filter list does not exist is displayed in the command output, the specified IPv4 prefix list failed to be configured. To re-configure it, run the ip ip-prefix command in the system view.
