Configuring Hub and Spoke

Configuring Hub and Spoke

In Hub and Spoke networking, a central site is deployed and all the other sites communicate through the central site. The central site controls communication between sites.

Pre-configuration Tasks

Before configuring Hub and Spoke, complete the following tasks:

  • Configure IGP on PE devices and P devices on the MPLS backbone network.

    NOTE:

    When RIP-1 runs on the backbone network, you need to enable LDP to search for routes to establish LSPs based on the longest match rule. For details, see Configuring LDP Extensions for Inter-Area LSPs in "MPLS LDP Configuration" in the S1720, S2700, S5700, and S6720 V200R010C00 Configuration Guide - MPLS.

  • Configure basic MPLS capabilities and MPLS LDP (or RSVP-TE) on PE devices and P devices on the MPLS backbone network.

  • Configure the IP addresses, through which the CE devices access the PE devices, on the CE devices.

NOTE:

You also need to configure VPN tunnel policies when VPN services need to be transmitted over TE tunnels or when multiple tunnels need to perform load balancing to fully use network resources. For detailed configuration, see Configuring Tunnel Policies.

Configuration Process

All the following tasks are mandatory. Perform these tasks in this sequence to complete the Hub and Spoke configuration.
