Team,
The Tasks below, have the same requirement but the configs are done
differently...are they equivalent? Here is what confuses me the most:
1- #ntp trusted-key <key> . I thought this command MUST always be included
in the client side whenever you config authntication. Nop, as shwed in LAB 2-
Vol 2 Tasks 6-1 page 101 DSG.
2- #ntp authenticate. I thought this command MUST always be included in both
the client and the server side whenever you config authntication. Nop, as shwed
in LAB 2- Vol 2 Tasks 6-1 page 101 DSG
3- #ntp server <x.x.x.x> and #ntp trusted-key <key>. I thought these commands
MUST always both be included in the client side whenever you config
authntication and needed to specify the source of NTP packets.
I have just realized one can have the following config instead: #ntp
server x.x.x.x source Lo1 key 1, as showed in R2.
How to know which one to use?
Thanks
BAuke
