Usage guidelines
This command enables the tunnel source to perform fragmentation check for IPv6 packets to be tunneled through an IPv6 over IPv4 tunnel. The tunnel source returns an ICMPv6 Packet Too Big message to the packet sending source and discards the packet if the packet size exceeds both of the following values:
· Outgoing interface MTU minus the IPv4 header length.
· The minimum IPv6 path MTU 1280 bytes.
Examples
# Enable IPv6 fragmentation check for packets to be tunneled.
<Sysname> system-view
[Sysname] tunnel ipv6-fragmentation-check enable
