Configuring A Hub-Spoke Network - HP FlexNetwork HSR6600 Configuration Manual

Configuring a hub-spoke network

Network requirements
The Spoke-CEs cannot communicate directly. They can communicate only through Hub-CE.
Configure EBGP between the Spoke-CEs and Spoke-PEs and between Hub-CE and Hub-PE to
exchange VPN routing information.
Configure OSPF between the Spoke-PEs and Hub-PE to implement communication between the
PEs, and configure MP-IBGP between them to exchange VPN routing information.

Configuration procedure
1. Configure an IGP on the MPLS backbone to ensure IP connectivity within the backbone:
# Configure Spoke-PE 1.
