Configuration Task



Configure the MPLS VPN backbone network.

Confirm requirements of VPN users.

  1. 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
  2. Determine the routing protocol used on the backbone network.

    RIP-1 cannot be used on the backbone network.

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 the CloudEngine 12800 and 12800E Series Switches Configuration Guide - IP Routing.

Enable MPLS on backbone devices.

Enable MPLS and configure the 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 MPLS LDP configuration, see the MPLS LDP Configuration in the CloudEngine 12800 and 12800E Series Switches Configuration Guide - MPLS.
  • For detailed RSVP-TE configuration, see the RSVP-TE Configuration in the CloudEngine 12800 and 12800E Series Switches Configuration Guide - MPLS.

In addition, configure VPN tunnel policies if VPN services need to be transmitted over TE tunnels or if load balancing needs to be performed between multiple tunnels. For detailed configuration, see Configuring and Applying a Tunnel Policy.

Configure MP-IBGP between PE devices.

See Establishing MP-IBGP Peer Relationships Between PE Devices.

Connect MPLS VPN users.

Configure VPN instances on the 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.
