dear all,
             i have a problem in NTP....

i have a third party stratum X(stratum 9) and in R1 i also have a local
master(stratum 11), r1 is getting clock from X and R@ is getting clock from
r1, the problem is R2 is no synchronising with R1...in R2 it shows...*Clock
is unsynchronized, stratum 16*

MY stratum is x

*r1*
*ntp clock-period 17207899
ntp master 11
ntp server 10.0.20.45 (ip address of X)*

 r1#sh ntp status
Clock is synchronized, stratum 10, reference is 10.0.20.45
nominal freq is 250.0000 Hz, actual freq is 249.5927 Hz, precision is 2**24
reference time is C9323E0D.15397840 (16:01:41.082 IST Tue Dec 19 2006)
clock offset is -860.8162 msec, root delay is 1.59 msec
root dispersion is 1703.00 msec, peer dispersion is 831.88 msec
