Example
Configuring Dynamic
IPv6-to-IPv4 Mappings
To do...
Display the NAT-PT session timeout
time
Display the NAT-PT fragment
session information
Display the dynamic NAT-PT
session information.
Display NAT-PT statistics
information.

mappings.
Clear all NAT-PT statistics
information
Network requirements
An IPv4 network is connected to an IPv6 network through a NAT-PT device -
Router B. Dynamic IPv6-to-IPv4 mappings are configured on Router B so that IPv6
hosts can access IPv4 hosts but IPv4 hosts cannot access IPv6 hosts.
