           Had a similar problem with RIP2 authentication over serial
   ports and I discovered this. Turn on authentication before defining
   the keys. With RIP2 do an "ip rip auth key test" on the interface and
   set mode to MD5 and then define your key and key-string, rather than
   defining the key first and then turning on authentication. This was
   the only way it would work for me. NTP may also be similar.
