Parameters
acl number acl-number: Specifies the IPv4 access control list (ACL) number, in the range of 2000 to
2999.
prefix natpt-prefix: Specifies the NAT-PT prefix, which is 96 bits in length.
Usage guidelines
For a packet from an IPv4 host to an IPv6 host, if the source IPv4 address matches the specified ACL, the
NAT-PT prefix is added to translate the source IPv4 address into an IPv6 address.
The natpt-prefix argument in the natpt v4bound dynamic command must be specified by the natpt prefix
command in advance.
Examples
# Configure a dynamic source address mapping policy for packets from IPv4 hosts to IPv6 hosts. Use ACL
2000 to match IPv4 packets and add the NAT-PT prefix 2001:: to translate the source IPv4 address into
an IPv6 address.
