	You need to be very careful if you're going to use routers as 
time servers.  See 
<http://ntp.isc.org/bin/view/Support/DesigningYourNTPNetwork#Section_5.6.>.

	Now, you could probably set up the routers as broadcast time 
servers, and they'd still be fine (not much extra load there, and no 
expensive associations between the servers and the clients to be 
worried about).  But don't set them up as manycast or unicast time 
servers, unless you want to run into the issues mentioned at the URL 
above.
