There are several ways to ensure the continuous end-to-end LSP between PE routers.  Learning Objectives: ã   Review of configuration of VPN, VRF. ã   Review route redistribution. ã   Understand and configure MPLS. ã   Understand and configure TE. 󰀲   󰁔󰁯󰁰󰁯󰁬󰁯󰁧󰁹 Routers P1, P2, P3 and P4 are in the core, just running OSPF in area 0. Each router has Loopback 0 with address 10.0.1.x (where x is the router number – P1 = 10.0.1.1).  4 Provider-edge routers PE1, PE2, PE3 and PE4 run OSPF in area 0 too; they have Loopback 0 with address 10.0.2.x. Each PE routers has iBGP with P3, that is the route-reflector for AS 100. All P and PE routers run LDP and are enabled for MPLS traffic-engineering. Both Customer1 and Customer2 have 3 sites: 1 HQ and 2 branch offices. HQs have a /25 subnet, branch offices a /26. Customer1 needs a full-mesh logical topology, with each site connecting directly to others sites. Customer2 needs a hub-and-spoke topology, where each branch office sends traffic through the HQ to reach the other site. Some clouds connected to Virtual PC Simulator are used to replace CE routers in order to lower system resources needed to run the topology. The VPCS config file is in the package (startup.vpc); you can find VPCS here: A MPLS Traffic Engineering (TE) tunnel is configured (but administratively down) between PE1 and PE3; it has an explicit path through P1 and P2.
