User Guidelines
IPv6 ACL is defined by a unique name. IPv4 ACL, IPv6 ACL, MAC ACL or
Policy Map cannot have the same name.
Every IPv6 ACL has implicit permit icmp any any nd-ns any, permit icmp any
any nd-na any, and deny ipv6 any any statements as its last match conditions.
(The former two match conditions allow for ICMPv6 neighbor discovery.)
The IPv6 neighbor discovery process makes use of the IPv6 network layer
service, therefore, by default, IPv6 ACLs implicitly allow IPv6 neighbor
discovery packets to be sent and received on an interface. In IPv4, the Address
Resolution Protocol (ARP), which is equivalent to the IPv6 neighbor
discovery process, makes use of a separate data link layer protocol; therefore,
by default, IPv4 ACLs implicitly allow ARP packets to be sent and received on
an interface.
