Section 4.3.2 says:
The MTU-probe MAY be multicast to All-RBridges, or unicast to a specific RBridge. The MTU-ack is normally unicast to the source of the MTU-probe to which it responds but MAY be multicast to All-RBridges.
It should say:
The MTU-probe MUST be multicast to All-IS-IS-RBridges or unicast to a specific RBridge. The MTU-ack is normally unicast to the source of the MTU-probe to which it responds but MAY be multicast to All-IS-IS-RBridges.
Notes:
TRILL IS-IS MTU PDUs are IS-IS PDUs and, when multicast, must be sent to the All-IS-IS-RBridges multicast address.
