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.
Before configuring Hub and Spoke, complete the following tasks:
Enable IPv6 on the devices.
Configure IGP on PEs and Ps in the MPLS backbone network.
Configure basic MPLS capability and MPLS LDP (or RSVP-TE) on PEs and Ps in the MPLS backbone network.
Configure the IP addresses, through which the CEs access the PEs, on the CEs.
All the following tasks are mandatory. Perform these tasks in this sequence to complete the Hub and Spoke configuration.
