Configuring TE Tunnels to Carry MPLS VPN Traffic
MPLS VPN traffic can be carried over MPLS traffic engineering (TE) tunnels.
Two different configurations are discussed in this section:
Transport of MPLS VPN traffic over TE tunnels between PE routers
Transport of MPLS VPN traffic over TE tunnels between P routers
Figure 6-28 shows both of these configurations.

Configuring TE Tunnels Between PE Routers
In this configuration, PE routers are configured as TE tunnel head-end and tail-end routers. P routers are configured as TE midpoint routers.
