IPv6 Prefix Lists
Filtering through prefix list processes routing information in specific order by applying pol-
icy defined in filter list. It is similar to access list but there are more detail rules as follow.
•
Allows all network information if there is no defined policy in prefix list.
•
Rejects specified network information unless policy applied to network in defined in
prefix list.
•
Distinguishes each policy with the assigned number and applies policy which has
the lowest number when there is more than one policy applied to one network.
Routers search policy in prefix list in order. For faster operation, user can make quick
search list by using
seq
provided from ip prefix-list. In order to view assigned number to
policy, use the
show ipv6 prefix-list
command.
Policies configured by user are automatically assigned number. If you do not configure it,
you should assign number to each policy by using the command,
ipv6 prefix-list seq
<1-
4294967295>.
