Parameter
rule-id: IPv6 ACL rule number in the range 0 to 65534.
deny: Defines a deny statement to drop matched packets.
permit: Defines a permit statement to allow matched packets to pass.
fragment: Indicates that the rule applies only to non-first fragments. The rule

that IP carries, source/destination address, source/destination port number, and
number of packets.

source { ipv6-address prefix-length | ipv6-address/prefix-length | any }: Specifies a
source address. The ipv6-address and prefix-length arguments specify a source
IPv6 address, and its address prefix length in the range 1 to 128. The any keyword
indicates any IPv6 source address.
