NTP gurus, I have two routers, R2 is configured to be NTP server, R7 is NTP client, I set the authentication on the server side, on client only the basic config, but client can still synchronize to the server: R2#sh run | be ntp ntp authentication-key 10 md5 02070658 7 ntp authentication-key 20 md5 12180416 7 ntp authenticate ntp trusted-key 10 ntp trusted-key 20 ntp clock-period 17179824 ntp update-calendar ntp server 172.10.27.3 key 20 end R2# ------------------------------------------ R7#sh run | be ntp ntp clock-period 17180004 ntp server 172.10.27.1 end R7#sh ntp s Clock is synchronized, stratum 10, reference is 172.10.27.1 nominal freq is 250.0000 Hz, actual freq is 249.9980 Hz, precision is 2**24 reference time is BEF831D9.8D762DCD (07:25:29.552 PDT Thu Jul 12 2001) clock offset is -62.3280 msec, root delay is 3.46 msec root dispersion is 939.09 msec, peer dispersion is 0.46 msec R7# I turned on the NTP debug, the packet R7 sent to R2 doesn't have any authentication key, why R2 still accept it? The images are 12.0. Thanks, Jerry _________________________________________________________ Do You Yahoo!?
