Video Session Question 1: Continue from previous slide. If a router R2 is connected to S1 and use S1 as its NTP server, then what is the stratum number of R2 clock? What's the ref clock in the output of running command on R2: R2# show ntp associations R1: 192.168.1.1 S1: 192.168.1.2 GPS NTP server R2 . Configure and Verify NTP (Cont.) The clock on S1 is configured to synchronize to R1 with the ntp server command and configuration is verified with the show ntp associations command. Output from the show ntp associations command verifies that the clock on S1 is no synchronized with R1 at 192.168.1.1 via NTP.R1 is a stratum 2 device, making S1 is stratum 3 device that can provide NTP service to other devices in the network. . si (config)# ntp server 192.168.1.1 si (config)# end si# show ntp associations address ref clock st when poll reach delay offset dis * 192.168.1.1 209.165.200.225 2 12 64 377 1.066 13.616 3.810 sys.peer, # selected, + candidate, outlyer, x falseticker, configured (output omitted) . si# show ntp status Clock is synchronized, stratum 3, reference is 192.168.1.1 nominal freq is 119.2092 Hz, actual freq is 119.2088 Hz, precision is 2**17 (output omitted R1 S1
