IPv6 Prefix List
Table 95 displays the individual devices and the IPv6 Prefix List features they support.
Configuring an IPv6 prefix list
Brocade devices support IPv6 prefix lists, which you can use for basic traffic filtering. You can
configure up to 100 IPv6 prefix lists.
An IPv6 prefix list is composed of one or more conditional statements that pose an action (permit
or deny) if a packet matches a specified prefix. 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, then use it as input to other commands or
processes, such as route aggregation, route redistribution, route distribution, route maps, and so
on. When a Brocade device interface sends or receives an IPv6 packet, it applies the statements
within the IPv6 prefix list in their order of appearance to the packet. As soon as a match occurs, the
device takes the specified action (permit or deny the packet) and stops further comparison for that
packet.
You can use permit statements in the prefix list to specify the traffic that you want to send to the
other feature. If you use deny statements, the traffic specified by the deny statements is not
supplied to the other feature.
To configure an IPv6 prefix list and use it as input to the RIPng distribute-list command, enter
commands such as the following.
Brocade(config)# ipv6 prefix-list routesfor2001 permit 2001:db8::/32
Brocade(config)# ipv6 router rip
Brocade(config-ripng-router)# distribute-list prefix-list routesfor2001 out
