Hi there Pranksters!
I think I have nailed the problems we have with NTP and getting the updates
to authenticate etc...
For R1 (master) I have the following config:
ntp authentication-key 1 md5 121A0C041104 7
ntp authenticate
ntp source Loopback0
ntp master 2
For R2 (Client):
ntp authentication-key 1 md5 05080F1C2243 7
ntp authenticate
ntp trusted-key 1
ntp clock-period 17179869
ntp source Loopback0
ntp server 1.1.1.1 key 1
The trick is the order the commands are typed in!
Always type them in the order they appear in the config file afterwards...
That means for instance on R1 I typed in the NTP authentication-key first,
then the ntp authenticate, then ntp source and at last ntp master.
I used the same procedure for R2.
When I show NTP associations detail I get the following output on the R2
(client):
1.1.1.1 configured, authenticated, our_master, sane, valid, stratum 2

7.52
filterror = 0.02 0.99 1.97 2.94 3.92 4.90 5.87

I hope it helps some of you out there that has been pulling your hair out
trying to figure out why it did not work!
