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 an 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.
{
Configure the VPN instance of VPN 1 on PE 3 to allow CE 3 to access the network.
{
Configure BGP as the PE-CE routing protocol, and redistribute routes of the CEs into the
PEs.
