Enabling dropping IPv6 packets that use IPv4-compatible IPv6 addresses
About dropping IPv6 packets that use IPv4-compatible IPv6 addresses
This feature enables the device to check the source and destination IPv6 addresses of the de-encapsulated IPv6 packets from a tunnel. If a packet uses an IPv4-compatible IPv6 address as the source or destination address, the device discards the packet.
