Configuration procedure

1. Set the IP address for each interface as shown in Figure 23. (Details not shown.)

2. Configure CE 1:

# Specify the local clock as the reference source, with the stratum level 1.

<CE1> system-view

[CE1] ntp-service refclock-master 1

3. Configure PE 1:

# Specify CE 1 as the symmetric-passive peer for VPN 1.

<PE1> system-view

[PE1] ntp-service unicast-peer vpn-instance vpn1 10.1.1.1

# Display the NTP session information and status information on PE 1 a certain period of time later.

The information should show that PE 1 has been synchronized to CE 1, with the stratum level 2.
