Lab 168 - Creating MPLS Topology

Prerequisites: CCNP level skills.

Note!
This topology layout is based on the new physical topology presented here.

Topology

Task 1
Using the physical topology presented here configure the IP addressing according to the following diagram. Make sure that all routers and switches can ping each other on a point-to-point basis (All loopbacks use 10.0.x.x/24 addresses where x=router number, sw1=7, sw2=8 etc.).

Pic. 1 - MPLS Topology Diagram.


Task 2
Once devices can ping each other on a point-to-point basis, enable OSPF on links between R1, R2, R3 and SW3 (core of our MPLS network) Advertise loopback addresses as /32 prefixes. Use AREA 0.
