Huawei AR1200 Series - Configuring Hub and Spoke; Establishing the Configuration Task

Procedure
l Run the display ip routing-table vpn-instance vpn-instance-name command to check
routing information about the specified VPN instance IPv4 address family on the PE.
l Run the display ip routing-table command to check routing information on the CE.
l Run the display ip vpn-instance [ vpn-instance-name ] interface command to check
information about the interface to which a specific VPN instance is bound.
----End
Example
Run the display ip routing-table vpn-instance vpn-instance-name command. If the VPN routes
related to the CE are displayed, it means the configuration succeeded.
Run the display ip routing-table command. If the routes to the peer CE are displayed on the
CE, it means the configuration succeeded.
Run the display ip vpn-instance [ vpn-instance-name ] interface command on the PE. If the
interface bound to a VPN instance is displayed, it means that the configuration succeeded.
3.5 Configuring Hub and Spoke
In the Hub and Spoke networking, an access control device is specified in the VPN, and users
communicate with each other through the access control device.
3.5.1 Establishing the Configuration Task
Before configuring Hub and Spoke networking, familiarize yourself with the applicable
environment, complete the pre-configuration tasks, and obtain the required data. This can help
you complete the configuration task quickly and accurately.
Applicable Environment
If all the users are required to access to a central access control device, the Hub and Spoke
networking is adopted. In the Hub and Spoke network, all the Spoke stations communicate
through the Hub station.
Pre-configuration Task
Before configuring Hub and Spoke, complete the following tasks:
l Configuring IGP on PE devices and P devices in the MPLS backbone network
l Configuring basic MPLS capability on PE devices and P devices in the MPLS backbone
network
l Configuring the IP addresses, through which the CE devices access the PE devices, on the
CE devices
Data Preparation
Before configuring Hub and Spoke, you need the following data.
