Use the undo ip ip-prefixcommand to remove an IPv4 prefix list or an item.

No IPv4 prefix list is configured by default.

An IPv4 prefix list is used to filter IPv4 addresses. It may have multiple items, each of which specifies a range of IPv4 prefix. The filtering relation among items is logic OR, namely, passing any item means the IPv4 prefix list is passed. If no item is passed, the IP prefix list cannot be passed.

The IP prefix range is determined by mask-lengthand [ min-mask-length,max-mask-length]. If both mask-lengthand [ min-mask-length,max-mask-length] are specified, then the IP address to be filtered must satisfy both of them.

If ip-addressmask-lengthis specified as 0.0.0.0 0, then only the default routes will be matched.

To match all the routes, use 0.0.0.0 0 less-equal32.

Examples # Create a routing policy named policy1 with node 10, matching mode as permit. Define an IP prefix list named p1 to permit only the routes in the network segment 10.0.192.0/8 and with mask length 17 or 18.
