Description:
MPLS Traffic Engineering (TE) has been widely deployed to satifisfy all kinds of requirements of traffic engineering for transport of services. Complexity of configuration has much negative effect on the MPLS TE deployment in the large-scale network. The document identifies the configuration issues for MPLS TE deployment and proposes a new mechanism, the service-driven mechanism, by which the setup of co-routed MPLS Traffic-Engineered Label-Switched Paths(TE LSPs) is triggered by the bidirectional service. Then the document proposes the framework for setting up service-driven co-routed MPLS TE LSP for L2VPN and L3VPN.

Description:
In some large scale L3VPN deployment scenarios like mobile backhaul network, it is required that tunnels between two PEs could be setup automatically driven by L3VPN service to reduce manual configuration effort. Moreover the tunnels must be setup co-routed for the goodness of performance monitoring and uniform protection behavior for link failure on two directions. This is described in [I-D.li- mpls-serv-driven-co-lsp-fmwk]. This document introduces a new BGP VT route based on [I-D.ni-bgp-ext-l3vpn-pm]. The route is utilized by on side PE to advertise Tunnel ID to other side PE, so inverse direction co-routed LSPs can be setup based on path information of member LSPs in the first tunnel.
