Sample NTP conguration
The 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 acts as an 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 the VRF.
To create this sample NTP conguration:
1
Congure the NTP server:
a Create a non-default VRF instance and assign an interface
to the 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
2 Congure an NTP client:
a Create a non-default VRF instance and assign an
interface to the VRF.
OS10(config)# ip vrf red
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
10.0.0.2/24
OS10(conf-if-eth1/1/1)# exit
OS10(config)#
