NTP Server

[PinkLips]

I have sseveral edge routers (2621XM) that connects to my backbone router (7206VXR). Is there a way I can get the edege routers to sych time with my core backbone router? Everytime we add a new edge router I have to run the #set clock command to match the time with the core router. Can someone give me a example of a edge and core configuration for NTP?



Thanks,
Nicole

sure all you have to do is use the core rtr as a ntp server (master) and peer the rest of the routers with it


on the core 72xx

Our core router 3750 (192.168.1.1)

confi t
ntp source FastEthernet0/0
ntp master 2 ***
ntp server 192.168.252.1 source FastEthernet0/0 prefer

***(2 is the stratum value from the atomic clock, since i am actual drawing the time from a netware server@192.168.252.1 inhouse (and dishing it out to other routers) i am using 2 instead of 1, if the rtr had it's own bios clock i'd choase 1 for the stratum value)


a branch router (2651XM)
ntp server 192.168.1.1 source FastEthernet0/0 prefer

i am not including all the fancy authentication stuff just to give you the meat and potatoes of what needs to be done.

good luck
