Configuration example for MPLS VPN time
synchronization in symmetric active/passive mode
Network requirements
As shown in
belong to VPN 1.
To synchronize time between PE 1 and CE 1 in VPN 1, perform the following tasks:
• Configure CE 1's local clock as a reference source, with the stratum level 2.
Configure CE 1 to operate in symmetric active mode.
•
• Specify VPN 1 as the target VPN.

Configuration procedure
Before you perform the following configuration, be sure you have completed MPLS VPN-related
configurations.
1. Assign an IP address to each interface, as shown in
PE 2, PE 2 and CE 3 can reach each other. (Details not shown.)
2. Configure CE 1:
# Enable the NTP service.
