Example for Configuring LDP over TE

This section provides an example for configuring LDP over TE. The configuration procedure involves the establishment of a TE tunnel and a remote LDP peer.

Networking Requirements

On the network shown in Figure 1, LSRB and LSRD are on the edge of a backbone network. LDP over TE is to be deployed on this network to allow an LDP LSP to across an RSVP-TE area. LDP services can be transmitted between LSRA and LSRB, and between LSRD and LSRE. In addition, TE services are transmitted between LSR B, LSRC, and between LSRC and LSRD. A TE tunnel destined for LSRD is established on LSRB, and an RSVP tunnel destined for LSRB is established on LSRD. Traffic between LSRA and LSRE needs to be transmitted through the tunnel. LDP over TE can transmit VPN services.

Configuration Notes

When configuring LDP over TE, note that the tunnel destination address must be the LSR ID of the egress.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Assign an IP address to each interface, configure the loopback address as the LSR ID, configure an IGP to advertise routes to the network segment connected to each interface and the host route to each LSR ID.

  2. Enable OSPF TE in a TE-aware area and establish an MPLS TE tunnel.

  3. Enable MPLS LDP in each non-TE-aware area and configure remote LDP peers at the edge of the TE-aware area.

  4. Configure the forwarding adjacency.

Data Preparation

To complete the configuration, you need the following data:

  • OSPF process ID and OSPF area ID

  • Policy for triggering the LSP establishment

  • Name and IP address of each remote LDP peer of LSRB and LSRD

  • Link bandwidth attributes of the tunnel

  • Tunnel interface number, IP address, destination address, tunnel ID, RSVP-TE tunnel signaling protocol, tunnel bandwidth, TE metric value, link cost on LSRB and LSRD

Procedure

  1. Assign an IP address to each interface.

    Assign an IP address to each interface in this section. For configuration details, see Configuration Files in this section.

  2. Configure OSPF to advertise the route to the network segment to which each interface is connected and the host route to each LSR ID. For configuration details, see Configuration Files in this section.
  3. Enable MPLS on each LSR. Enable LDP to set up LDP sessions between LSRA and LSRB, and between LSRD and LSRE. Enable RSVP TE to establish RSVP neighbor relationships between LSRB and LSRC, and between LSRC and LSRD.
