natpt v4bound dynamic
Syntax natpt v4bound dynamic acl number acl-number prefix natpt-prefix

View System view
Parameter acl-number: IPv4 access control list (ACL) number, in the range of 2000 to 2999.
natpt-prefix: NAT-PT prefix, 96 bits in length.
Description Use the
natpt v4bound dynamic command to configure a dynamic IPv4-to-IPv6
mapping.
Use the
undo natpt v4bound dynamic command to remove the dynamic
mapping.
For a packet from an IPv4 host to an IPv6 host, if the source IPv4 address complies
with the specified ACL rule, a NAT-PT prefix will be added to translate the source
IPv4 address into an IPv6 address.

CAUTION: The natpt-prefix argument in the natpt v4bound dynamic command
must be specified by the natpt prefix command in advance.
Example # Use ACL 2000 to identify the source address of an IPv4 packet and add the
NAT-PT prefix 2001:: to translate the source address into an IPv6 address.
