III. Configuration procedure
Configuring OSPF on the MPLS backbone network
Configuring basic MPLS capability on the MPLS backbone network
Configuring a VPN instance on PEs.
Configuring MP-BGP
1) Configure OSPF as the IGP protocol on the MPLS backbone network; making
OSPFs on PEs can learn routes from each other. Create OSPF neighbor between
ASBR-PE and PE in the same AS.
