Summary of Basic BGP/MPLS IP VPN Configuration Tasks

**Table 1** Basic BGP/MPLS IP VPN configuration tasks
Configuration Task	Sub-task	Configuration
Configure the MPLS VPN backbone network.	Confirm requirements of VPN users.	Determine number of devices and interfaces based on the network scale, including: Number of users Number of VPNs for each user Number of VPN instances for each VPN Routing protocol used on the backbone network NOTE: When RIP-1 runs on the backbone network, you need to enable LDP to search for routes to establish LSPs based on the longest match rule. For details, see Configuring LDP Extensions for Inter-Area LSPs in "MPLS LDP Configuration" in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - MPLS. Configuring a Dynamic MPLS TE Tunnel in "MPLS TE Configuration" in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - MPLS.
	Configure routing between backbone devices.	Configure an Interior Gateway Protocol (IGP) on the PE and P devices of the MPLS backbone network to achieve IP connectivity on the backbone network. For detailed configuration, see S2720, S5700, and S6700 V200R019C10 Configuration Guide - IP Unicast Routing Configuration Guide.
	Enable MPLS on backbone devices.	Enable MPLS and configure a Label Distribution Protocol (LDP) to set up public network tunnels. The LDP can be MPLS LDP or Resource Reservation Protocol-Traffic Engineering (RSVP-TE). For detailed configuration, see the MPLS LDP Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - MPLS. For detailed configuration, see the Configuring a Dynamic MPLS TE Tunnel in "MPLS TE Configuration" in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - MPLS. You also need to configure VPN tunnel policies when VPN services need to be transmitted over TE tunnels or when multiple tunnels need to perform load balancing to fully use network resources. For detailed configuration, see Configuring Tunnel Policies.
	Configure MP-IBGP between PE devices.	See Establishing MP-IBGP Peer Relationships Between PE Devices.
Connect MPLS VPN users.	Configure VPN instances on PE devices.	See Configuring a VPN Instance on a PE Device.
	Bind VPN instances to interfaces.	See Binding a VPN Instance to an Interface.
	Configure route exchange between PE and CE devices.	See Configuring Route Exchange Between PE and CE Devices.
