the message says that a HELLO packet contains a reserved circuit type equal to zero, while the system was expecting to get type 1 or 2 or 1/2. If you are running some sort of an emulator, then it is a known glitch which you might rectify by simply having the instances restarted. If this is a real gear, you might do a interface reset. You also could set up a sniffer capture and dig it a bit further. From troubleshooting point of view worth of interest is to check the full log on the node you're seeing these messages, as well as to check its peer on gig3/0(ca01.1320.0038).
