Connectivity is OK, I can ping any address loopbacks also.
Here is screen shot from 3620 in terms of ntp commands on my router.
WG1R3(config)#ntp ?
access-group Control NTP access
authenticate Authenticate time sources
authentication-key Authentication key for trusted time sources
broadcastdelay Estimated round-trip delay
clock-period Length of hardware clock tick
master Act as NTP master clock
max-associations Set maximum number of associations
peer Configure NTP peer
server Configure NTP server
source Configure interface for source address
trusted-key Key numbers for trusted time sources
I set up clock immediately after router (3620) came up and it not helped.
What I also don't understand is why on 3620 association status is like this:
address ref clock st when poll
reach delay offset disp
~127.127.7.1 .LOCL. 0 - 64 0 0.0 0.00
16000.
* master (synced), # master (unsynced), + selected, - candidate, ~ configured
