Default Configuration
The IPv6 transition-mechanism global support mode is disabled.
Command Mode
Interface Configuration (Tunnel) mode
User Guidelines
The system can be enabled to ISATAP tunnel. When enabled, an automatic tunnel
interface is created on each interface that is assigned an IPv4 address.
Note that on a specific interface (for example, port or VLAN), both native IPV6 and
transition-mechanisms can coexist. The host implementation chooses the egress
interface according to the scope of the destination IP address (such as ISATAP or
native IPv6).
Example
The following example configures an IPv6 transition mechanism global support
mode.
Console(config)#
interface tunnel
1
Console(config-tunnel)#
tunnel mode ipv6ip isatap
