Scenario:
Given the following diagram, configure IPX on the Ethernet links of
Router_A and Router_C only. Provide full connectivity using Router_B
as a frame relay switch.

Time Protocol
Using the diagram below configure Network Time Protocol.
Send_ntp will provide time to Receive_ntp.
Use your current time and location for your clock settings.
此主题相关图片如下:
Solution:
Set the appropriate time and time zone for the router that will act as
your time server.
Also set the time server using the "ntp master" command.
At the appropriate interface broadcast the NTP protocol.

To configure the receiving router, just point it to the time server.
Before router is configured to receive time from NTP server:
receive_ntp#sh clock
*00:05:04.359 UTC Mon Mar 1 1993
receive_ntp#config t
Enter configuration commands, one per line. ...
End with CNTL/Z.
