Sim 10: MPLS LDP and Layer 3 VPN

Blueprint 2.1, 2.2

Difficulty Time target Devices Faults
Hard 30 minutes 5 x IOSv 3

Scenario

A service provider (AS 65000) carries customer A between two sites with an MPLS Layer 3 VPN. R1 and R3 are PE routers, R2 is a P router. The core runs OSPF area 0 for loopback reachability and LDP for labels. The PEs exchange VPNv4 routes over an iBGP session between loopbacks. Customer A's routers R4 (site 1, AS 65104) and R5 (site 2, AS 65105) peer with their PE over eBGP inside VRF CUST-A.
