Command Usage
◆
If a non-default value is configured, an MTU option is included in the router
advertisements sent from this device.
◆
The maximum value set by this command cannot exceed the MTU of the
physical interface, which is currently fixed at 1500 bytes.
◆
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.
