COMMAND USAGE
◆ IPv6 routers do not fragment IPv6 packets forwarded from other
routers. However, traffic originating from an end-station connected to
an IPv6 router may be fragmented.

◆ IPv6 must be enabled on an interface before the MTU can be set.
EXAMPLE
The following example sets the MTU for VLAN 1 to 1280 bytes:
Console(config)#interface vlan 1
Console(config-if)#ipv6 mtu 1280
Console(config-if)#
