Usage guidelines
To avoid fragmentation and delay, set the DF bit for tunneled packets. Make sure the path MTU is
larger than the tunneled packet length. To avoid discarding tunneled packets whose length is larger
than the path MTU, do not set the DF bit.
This command is not supported on a GRE/IPv6 tunnel interface and an IPv6 tunnel interface.

Usage guidelines
This command 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.
Examples
# Enable dropping IPv6 packets that use IPv4-compatible IPv6 addresses.
<Sysname> system-view
[Sysname] tunnel discard ipv4-compatible-packet

tunnel tos

Use tunnel tos to set the ToS of tunneled packets.
