I believe Cisco IOS does indeed broadcast to all-1s by default, but I make
it broadcast to the subnet-broadcast-address like this:
interface FastEthernet0/1
ip address 172.17.1.1 255.255.255.0
ip broadcast address 172.17.1.255
ntp broadcast key 1001 destination 172.17.1.255
ntp authenticate
ntp authentication-key 1001 md5 <password-for-bcasts>
ntp authentication-key 1002 md5 <password-for-peers>
ntp trusted-key 1001
ntp trusted-key 1002
ntp broadcastdelay 3000
ntp server 158.43. etc. etc.
ntp peer 172.17.6.200 key 1002
ntp peer 172.17.7.200 key 1002 etc. etc.
Apologies for being so late responding to this.
I was on the verge of responding, when I discovered my authentication was
"broken".
Hope it is still of interest.
Mike.
