Clear3
When the transmitter sends the Reset-Ack or when the receiver receives a Reset-ACK, they must reset the sequence number to zero, clear the compression dictionary, and resume sending and receiving compressed packets. (irt.org)
The transmitter must clear its compression dictionary and respond with a Reset-Ack each time it receives a Reset-Request, because it cannot know if previous Reset-Acks reached the receiver. (irt.org)
The receiver MUST clear its compression dictionary each time it receives a Reset-Ack, because the transmitter will have cleared its compression dictionary. (irt.org)
