This section provides an example for configuring virtual cluster access.

Networking Requirements

A large number of devices are deployed on the access ring of an IP radio access network (RAN), and the existing bearer techniques are complex in deployment. This situation causes high operation and maintenance (O&M) costs and poor network scalability. To reduce O&M costs and improve network scalability, configure virtual cluster access to carry access services.

As shown in Figure 2-8, AP1 and AP2 are connected to the base stations, and the primary and secondary masters are deployed on the access ring. Configure virtual cluster access on AP1, AP2, and the primary and secondary masters, and establish virtual paths (VPs) and virtual circuits (VCs) from AP1 and AP2 to the primary and secondary masters to carry packets from the base stations.

Table 2-3 Interface IP addresses

Device Name	Interface Name	IP Address
AP1	Loopback0	1.1.1.1/32
	GigabitEthernet0/1/1	10.1.2.1/30
	GigabitEthernet0/1/2	10.1.3.1/30
	GigabitEthernet0/1/3	192.168.0.1/24
AP2	Loopback0	2.2.2.2/32
	GigabitEthernet0/1/1	10.1.2.2/30
	GigabitEthernet0/1/2	10.2.4.1/30
	GigabitEthernet0/1/3	192.168.1.1/24
MasterA	Loopback0	3.3.3.3/32
	GigabitEthernet0/1/1	10.1.3.2/30
	GigabitEthernet0/1/2	10.3.4.1/30
MasterB	Loopback0	4.4.4.4/32
	GigabitEthernet0/1/1	10.2.4.2/30
	GigabitEthernet0/1/2	10.3.4.2/30

Virtual cluster access is deployed on the access ring of an IP RAN, and the APs have the same virtual cluster access configurations for different services, such as Ethernet and Asynchronous Transfer Mode (ATM)/time division multiplexing (TDM) services. This example provides only virtual cluster access configurations.

Configuration Roadmap

The configuration roadmap is as follows:

Assign an IP address to each interface and configure a loopback interface address as a management IP address on each node.
Enable virtual cluster access globally on each node to establish a virtual cluster access Intermediate System to Intermediate System (IS-IS) process.
Assign a management IP address to each node and configure the primary and secondary masters to which each AP belongs to establish Master Slave Control Protocol (MSCP) channels and VP protection groups.
Enable virtual cluster access on each node's interfaces.
Establish Remote-AP interfaces on the primary and secondary masters and bind the interfaces to the APs' AC interfaces to establish VCs.

Data Preparation

To complete the configuration, you need the following data:

IP addresses of directly connected interfaces and loopback interface addresses on each node
Management IP address of the primary master to which AP1 and AP2 belong: 3.3.3.3; management IP address of the secondary master to which AP1 and AP2 belong: 4.4.4.4
Number of the Remote-AP interface on the primary master connected to AP1: 11; number of the Remote-AP interface on the primary master connected to AP2: 21; number of the Remote-AP interface on the secondary master connected to AP1: 12; number of the Remote-AP interface on the secondary master connected to AP2: 22

Procedure

Assign an IP address to each interface and configure a loopback interface address as a management IP address on each node.
For configuration details, see "Configuration Files" in this section.

Enable virtual cluster access globally on each node.
