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.
Solution
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.).

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.
