Mpls L3Vpn Configuration Task List; Configuring Basic Mpls L3Vpn; Configuration Prerequisites - HP 12500 Series Configuration Manual

You can configure static routes, RIP, OSPF, IS-IS, eBGP, or iBGP between MCE and VPN site and between
MCE and PE.
NOTE:
To implement dynamic IP assignment for DHCP clients in private networks, you can configure DHCP server
or DHCP relay agent on the MCE. The IP address spaces for different private networks cannot overlap.

Configuration prerequisites

Before you configure basic MPLS L3VPN, complete the following tasks:
• Configure an IGP for the MPLS backbone (on the PEs and Ps) to ensure IP connectivity

Remarks
By configuring basic MPLS L3VPN, you can construct
simple VPN networks over an MPLS backbone.
To deploy special MPLS L3VPN networks, such as
inter-AS VPN, nested VPN, and multi-role host, you
also need to perform some specific configurations in
addition to the basic MPLS L3VPN configuration. For
more information, see the related sections.
