In prefix lists with multiple statements, you can specify a sequence number for each statement. The specified sequence number determines the order in which the statement appears in the prefix.
You can configure an IPv6 prefix list on a global basis and use it as input to other commands or processes, such as route aggregation, route redistribution, route distribution, and route maps. When a device sends or receives an IPv6 route, it applies the statements in the IPv6 prefix list in their order of appearance to the packet. When a match occurs, the device takes the specified action (permit or deny the packet) and stops further comparison for that route.
You can use permit statements in the prefix list to specify the route that you want to send to the other feature. If you use deny statements, the route specified by the deny statements is not supplied to the other feature.
A device supports IPv6 prefix lists, which you can use for basic route filtering. You can configure up to 100 IPv6 prefix lists.
You must specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as documented in RFC 4291. You must specify the prefix-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prefix parameter and precede the prefix-length parameter.
