To configure a peer-to-peer association between the router and another device, you must also configure
the router as a peer on the other device.
You can configure multiple peers and servers, but you cannot configure a single IP address as both a peer
and a server at the same time.
To change the configuration of a specific IP address from peer to server or from server to peer, use the
no
form of the
peer
or
server
command to remove the current configuration before you perform the
new configuration. If you do not remove the old configuration before performing the new configuration,
the new configuration does not overwrite the old configuration.

DETAILED STEPS
Purpose
Command or Action
configure
Step 1
Enters NTP configuration mode.
ntp
Example:
RP/0/RP0/CPU0:router(config)# ntp
Step 2
Forms a server association with another system. This step can be
repeated as necessary to form associations with multiple devices.

Step 3
Example:
