After successfully configuring the previous frame-relay lab you feel it’s time to try and run OSPF over this frame-relay link. OSPF knows many different network types and every type has a different solution, up to you to try them all out!
Hint: this lab uses the same topology as the “Frame-Relay Basics” lab, make sure you configured this lab first, then continue with this one.
- Create loopbacks on all routers:
Paris: 22.214.171.124 /24
Berlin: 126.96.36.199 /24
Stockholm: 188.8.131.52 /24
- Configure OSPF on all routers using the point-to-multipoint interface (192.168.123.X subnet).
- Advertise all loopbacks in OSPF.
- Paris should be the OSPF designated router.
- Configure the OSPF network type on all routers to “Broadcast”, ensure you have full connectivity to all subnets.
- Configure the OSPF network type on all routers to “Non-Broadcast”, ensure you still have full connectivity.
- Configure the OSPF network type on all routers to “Point-to-Multipoint”, ensure you still have full connectivity.
- Configure the OSPF network type on all routers to “Point-to-Multipoint non-broadcast”, ensure you still have full connectivity.
It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the routing protocols for CCNP.
Would you like to be a master of routing too? In a short time without having to read 900 page books or google the answers to your questions and browsing through forums?
I collected all my knowledge and created a single ebook for you that has everything you need to know to become a master of routing.
You will learn all the secrets about OSPF, network types, frame-relay and more.
