Hi all,
I've been having problems getting NTP to work as expected.
I have 3 2500's, rtr A, rtrB, and rtrC connected to each other via a common
ethernet segment.
rtrA-----------------rtrB
|
|
rtrC
rtrA config:
ntp master 6
rtrB config:
ntp master 10
ntp server 10.0.1.1 (rtrA's lo0 addr)
rtrC config:
ntp peer 10.0.1.1
ntp peer 10.0.2.2 (rtrB's lo0 addr)
Problems and issues:
Before rtrC was configured, rtrB sync'ed with rtrA as expected, but now rtrA
won't sync with itself and rtrC is syncing with rtrB. Shouldn't rtrC sync
with rtrA since it has a lower stratum?
Why doesn't rtrA sync with itself? Show ntp asso det shows "insane, invalid,
etc.
rtrA and rtrB had sync'ed up properly before I configured authentication but
then it stopped working correctly so I removed the authentication and now it
won't work. Any ideas as to what's going on?
When doing authentication, is the following necessary?
ntp client:
ntp server a.b.c.d key # ( Is this needed when the command, ntp
trusted key #, is used?)
ntp trusted key # ( Is this needed if the key# option is
used in the above command?)
ntp authentication-key # md5 <password>
ntp authenticate
According to Doyle, volume II, the command, ntp trusted key # isn't needed on
the ntp master, but when I removed it from the master, ntp stopped working?
Doyle isn't wrong on this point is he?
Thanks for any insight you can provide, Jim
