Step 3 Create Ethernet private line services
3.4 Configuration Example (VCTRUNK-Shared EVPL Services)
This topic uses an example to describe how to plan the service parameters and complete the entire process of configuring the parameters of each NE according to the VCTRUNK-shared EVPL service requirements.
3.4.1 Networking Diagram
The networking diagram forms the foundation of service planning. In the following example, the networking diagram shows the NE networking mode and service requirements.
3.4.2 Service Planning
According to the service requirements and the equipment specifications that are shown in the networking diagram, the network planning department can plan all the parameters that are required for configuring the new Ethernet services of the NEs.
3.4.3 Configuring NE1
You can configure the VCTRUNK-shared Ethernet private line services of NE1 based on the parameters of the service planning, by using the NMS.
3.4.4 Configuring NE2
You can configure the VCTRUNK-shared Ethernet private line services of NE2 based on the parameters of the service planning, by using the NMS.
3.4.1 Networking Diagram
The networking diagram forms the foundation of service planning. In the following example, the networking diagram shows the NE networking mode and service requirements.
As shown in Figure 3-10, NE1 and NE2 are the OptiX RTN 600 NEs configured with the IDU 620. 16xE1 services exist between NE1 and NE2. The new service requirements are as follows:
l The two branches of User D are located at NE1 and NE2, and need to communicate with
each other.
l The two branches of User E are located at NE1 and NE2, and need to communicate with
each other.
l The services of User D need to be isolated from the services of User E. The traffic of User
D and User E, however, is supplementary to each other, and thus can share the 20 Mbit/s bandwidth.
l The Ethernet equipment of User D and User E provide 100 Mbit/s Ethernet electrical ports
of which the working mode is auto-negotiation, and does not support VLAN. Figure 3-10 Networking diagram
