Information
The ip nd mtu command sets the value advertised to routers. It does not set the actual MTU rate. For
example, if ip nd mtu is set to 1280, the interface will still pass 1500-byte packets.
The mtu command sets the actual frame size passed, and can be larger than the advertised MTU. If the
mtu setting is larger than the ip nd mtu, an error message is sent, but the configuration is accepted.
% Error: nd ra mtu is greater than link mtu, link mtu will be used.
