3.2 BGP/MPLS VPN Configuration

Note:
If you have configured both L2VPN and L3VPN services, L3VPN service must comply
with L2VPN service. If you remove L2VPN service, you can go on using L3VPN
service.
To configure MPLS VPN it is required to complete the following procedures in general:
Configure basic information on PE, CE and P.
Establish the logical or physical link with IP capabilities from PE to PE.
Advertise and update VPN network information.
I. CE router
Only static route, RIP, OSPF or EBGP is configured for VPN routing information
exchange with the PE connected, without MPLS.
II. PE router
It implements MPLS/BGP VPN core functions, so its configuration is a bit complicated,
including:
Configure MPLS basic capacity, joint maintenance of LSP with P router or other
PE router
Configure BGP/MPLS VPN site, i.e. VPN instance
Configure static route, RIP, OSPF or MP-EBGP, for VPN routing information
exchange with CE.
Configure IGP, for intra-PE interconnection.
Configure MP-IBGP, for VPN routing information exchange between PEs.
III. P router
MPLS basic capacity is configured, to support LDP and MPLS forwarding.
The following are detailed configurations.

3.2.1 Configuring CE Router

Only basic configuration is required on CE router, for routing information exchange with
PE router. Currently route switching modes available include static route, RIP, OSPF,
EBGP, VLAN subinterface etc.
