All,

I'm working on an NTP problem and I need some help. This is just a =
basic 2 router ntp setup. I am trying to use md5 authentication but it =
doesn't seem to be taking. Here are the configs:

Router 1:
ntp authentication-key 1 md5 02050D480809 7
ntp authenticate
ntp trusted-key 1
ntp master 2

Router 2:
ntp authentication-key 1 md5 121A0C041104 7
ntp authenticate
ntp trusted-key 1
ntp clock-period 17179866
ntp server 10.10.10.1 key 1

On router 2, I do a show ntp status and get (no "authenticated").
Clock is synchronized, stratum 3, reference is 10.10.10.1
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is =
2**24
reference time is BE028762.8F9D272D (06:12:50.560 UTC Sun Jan 7 2001)
clock offset is -2.2075 msec, root delay is 1.88 msec
root dispersion is 2.37 msec, peer dispersion is 0.12 msec

In ECP1 we configured this with ntp peers and it worked fine. Just =
doesn't seem to be taking when its between a master and client.

Any thoughts would be greatly appreciated.
Bill
