Configure IPv6 Extended ACL
IPv6 extended ACL can make the classification rule according to the IPv6 protocol number, source IPv6 address, destination IPv6 address, source TCP/UDP port number, destination TCP/UDP port number, packet priority, fragment tag, and TCP tag, so as to filter the packets.
Configuration Condition
None
Configure IPv6 Extended ACL
IPv6 extended ACL name can use the number and also can use the customized character string. If the IPv6 extended ACL name adopts the numbers, we can configure the maximum quantity limitation of ACL; if adopting the customized character string, there is no limitation for the maximum quantity of ACL. The user can select the ACL name as desired.

-
When using the ipv6 access-list extended command to create the IPv6 extended ACL, the ACL can be created only after configuring the rules in the IPv6 extended ACL configuration mode.
- Sequence means the order number of the rule in the ACL. ACL matches and filters the packet strictly according to the order from small sequence to large sequence. The rule with the small sequence first takes effect. When all rules do not match, execute the default drop action, that is, all the packets not permitted to pass are dropped.
Configure IPv6 Extended ACL Named by Numbers
The IPv6 extended ACL named by numbers can let the user identify the type of the ACL quickly. However, the IPv6 extended ACL named by numbers has some limitations. For example, the ACL quantity is limited.

If the ACL with the specified sequence does not exist, create one new ACL and add new rules. If the ACL with the specified number exists, just add new rules.
