As the senior network engineer for a Dutch fishing company you are responsible for connecting all the different branch offices to the main network. The WAN technology you are using is Frame Relay, and you need to run OSPF over this WAN connection. One of the restrictions is that you are unable to send broadcast traffic on this frame-relay link.
- The frame-relay switch has been preconfigured for you, as you can see in the topology picture the following PVC’s has been configured:
Router Barracuda to Salmon:
Barracuda: DLCI 102
Salmon: DLCI 201
Router Barracuda to Herring:
Barracuda: DLCI 103
Salmon: DLCI 301
- Router Barracuda is the “Hub” router and the other 2 routers are the “Spoke” routers.
- Do not change any configuration on the Frame-Relay switch.
- Configure the following IP addresses:
S0/0: 192.168.123.1 /24
L0: 188.8.131.52 /24
S0/0: 192.168.123.2 /24
L0: 184.108.40.206 /24
S0/0: 192.168.123.3 /24
L0: 220.127.116.11 /24
- Configure all serial interfaces for encapsulation Frame-Relay.
- Disable Frame-relay inverse arp on all serial interfaces.
- Configure the correct frame-relay map statements on all routers and make sure you can ping every IP address. You are not allowed to use the “broadcast” command.
- Configure the OSPF network type to “non-broadcast” on all serial interfaces.
- Configure OSPF on all 3 routers, make sure you have full connectivity. All IP addresses including the loopbacks should be reachable.
- Make sure router Salmon and Herring can never be the Designated or Backup designated router.
It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the protocols for CCNP.
Would you like to be a master of networking 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 CCNP.
You will learn all the secrets about OSPF network types, frame-relay settings and more.
Does this sound interesting to you? Take a look here and let me show you how to Master CCNP ROUTE!
