HP MSR2000 Configuration Manual page 303

CE 1 and CE 2 reside in the same site. CE1, CE2, and CE 3 all use AS number 600.
• To avoid route loss, configure BGP AS number substitution on PEs.
To avoid routing loops, configure the same SoO attribute on PE 1 and PE 2 for CE 1 and CE 2.

Configuration procedure
1. Configure basic MPLS L3VPN:
Configure OSPF on the MPLS backbone to allow the PEs and P device to learn the routes of the
loopback interfaces from each other.
Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs.
Establish MP-IBGP peer relationship between the PEs to advertise VPN IPv4 routes.
Configure the VPN instance of VPN 1 on PE 1 to allow CE 1 to access the network.
Configure the VPN instance of VPN 1 on PE 2 to allow CE 2 to access the network.
