Sample interconnection VLAN configuration

The following figure shows a sample configuration of an interconnection of VLANs across a VPLS backbone.

Verify that the following preconfigurations are complete:

Ensure that the appropriate preconfigurations have been performed on the OmniSwitch devices.
- pre-discovery CLI modifications
- SNMP trap forwarding to the NFM-P
- discovery including mediation configuration with the CLI user names and passwords
- ports are configured as access (ports that are part of the VLAN) and network (ports that are used for uplinks)
- configure protocol to manage topology loops, such as MSTP or RSTP, using CLI
Configure OmniSwitch ports as access and network, as required, from the navigation tree.
OmniSwitch devices that belong to the ring, and the 7450 ESS that the ring connects to, must be added to the ring group.

The following high-level tasks are required to configure this sample interconnection of VLAN services.


1	Ensure that the required configurations are completed to equipment as described in Configuration tasks , including access and network ports, enabling CLI configuration on managed OmniSwitch devices, and configuring and distributing policies.
2	Create VLAN services using a series of configuration forms. Ensure that the VLAN created for the ring group uses ID 444.
3	Configure the VPLS: Ensure that the encapsulation value of the ports that contain the SAPs on the 7450 ESS matches the VLAN ID of each VLAN service in the ring group. Ensure that the encapsulation value of the ports that contain the SAPs on the 7450 ESS at each VPLS site is Dot1 Q. See To create a VPLS for more information about creating a VPLS.
4	Create a composite service to interconnect the VLAN services with the VPLS. Create the composite service. Define general properties for the composite service. Specify the services that are participating in the composite service. You can specify multiple services in one operation. Create SCP-to-SCP connectors to link the dot1q-encapsulated VPLS SAP and the adjacent L2 switch uplinks of the VLAN ring group. See Chapter 85, Composite service management for more information about creating composite services.
