Hi guys,
 
This doesn't make much sense to me.
 
R3 is getting ntp time from BB3.
 
R3(config)#do r | in ntp
ntp authentication-key 1 md5 123A2C243124 7
ntp authenticate
ntp trusted-key 1
ntp server 204.12.1.254 key 1
 
 
BB3's config's
 
BB3#r | in ntp
ntp authentication-key 1 md5 0802657D2A36 7
ntp clock-period 17179837
ntp master 4
ntp server 172.16.4.1
 
As you can see, both R3 and BB3 are using key 1.
 
But, in the debug on R3, it shows key 0. Why is that?
 
.Mar 1 06:29:34.518: Authentication key 0
.Mar 1 06:29:34.518: NTP: packet from 204.12.1.254 failed validity tests 10

.Mar 1 06:31:42.520: NTP: packet from 204.12.1.254 failed validity tests 10

TIA, Tim
