Licensing Requirements and Limitations for IPv6 over IPv4 Tunnels

Involved Network Elements

Other network elements are not required.

Licensing Requirements

The IPv6 function must be enabled for the IPv6 over IPv4 tunnel function. The IPv6 function is controlled by a license. By default, the IPv6 function is disabled on a new device. To use the IPv6 function, apply for and purchase the license from the device supplier.

For details about how to apply for a license, see Obtaining Licenses in the S7700 and S9700 Series Switches License Usage Guide.

Feature Support in V200R019C10

All models of S7700 series switches support the IPv6 over IPv4 tunnel. Pay attention to the following:

The XGE interface connected to the ET1D2IPS0S00, ET1D2FW00S00, ET1D2FW00S01, ET1D2FW00S02, or ACU2 card does not support the IPv6 over IPv4 tunnel.

Feature Limitations

• The X1E series cards support the IPv6 over IPv4 tunnel function since V200R009C00.

• The X2E, X2H, and X2S series cards support the IPv6 over IPv4 tunnel function since V200R010C00.

• In the 6PE scenario, MPLS TE tunnels cannot be used on IPv4 backbone networks or public networks.
