Lab 177 - MPLS Overlapping VPNs

Prerequisites: CCNP level skills.

This lab layout is based on the new physical topology presented here. This lab assumes that you have successfully configured ALL previous MPLS labs.

As per recommendation ALL loopback addresses on P and PE routers will use /32 network mask! 
PE routers are: R1, R3, SW3.
P router is: R2
All other devices are CE routers in this MPLS topology.

Task 1
Configure MPLS VPNs such that subnets advertised by SW1 (VRF C) can reach the ones advertised by SW2 (VRF A). Ensure that SW1 CANNOT reach prefixes advertised by R4 and R5 (VRF A), and that SW2 cannot reach subnets advertised by SW4 (VRF C)

Restore the Lab 175 configuration after you have completed Lab 176 tasks.
