Configuring Bgp As Number Substitution - HP MSR2000 Configuration Manual

Configuring BGP AS number substitution

Network requirements
As shown in
The two CEs have the same AS number, 600.
Configure BGP AS number substitution on the PEs to enable the CEs to communicate with each other.

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 2 to allow CE 2 to access the network.
Configure the VPN instance of VPN 1 on PE 1 to allow CE 1 to access the network.
Configure BGP as the PE-CE routing protocol, and redistribute routes of CEs into PEs.
Figure 74, CE 1 and CE 2 belong to VPN 1 and are connected to PE 1 and PE 2, respectively.
