Sample NTP conguration
Following example shows an NTP master(11.0.0.2), server(10.0.0.1), and client(10.0.0.2) connected through a non-default VRF instance
(VRF red). OS10 System acts as NTP server to synchronize its clock with the NTP master available in the non-default VRF instance red
and provides time to NTP clients in that VRF instance.
Figure 1. Sample NTP conguration
To create this sample NTP conguration, perform the following steps:
1 Congure the NTP server using the following steps:
a Create a non-default VRF instance and assign an interface to that VRF.
OS10(conf-vrf)# exit
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# no switchport
OS10(conf-if-eth1/1/1)# ip vrf forwarding red
OS10(conf-if-eth1/1/1)# ip address 10.0.0.1/24
OS10(conf-if-eth1/1/1)# exit
OS10(config)# interface ethernet 1/1/5
OS10(conf-if-eth1/1/5)# no switchport
OS10(conf-if-eth1/1/5)# ip vrf forwarding red
