As a true coffee addict and network junkie you are working on the network of a world famous coffeeshop. Today your caffeine rush kicks in and you have a sudden desire to clean up some of the routing tables on the company routers. Let's see what you can do here with a couple of prefix-lists. Black......no sugar, no milk!
- All IP addresses have been preconfigured for you.
- EIGRP AS12 has been preconfigured for you.
- Router Mint advertises a bunch of prefixes to router Vanilla, take a quick look at the routing table to see them.
- You are only allowed to use one prefix-list.
- Create a single prefix-list statement to filter out all /32 networks in the 18.104.22.168 range, as a result the 22.214.171.124 /30's should still be in Vanilla's routing table.
- Create a single prefix-list statement to filter out any subnet in the Class B network range.
- Create a single prefix-list statement to filter out any subnet in the Class C network range that has a subnetmask of /25, /26 or /27. As a result all the Class C subnets with /24 or higher than /27 should still be in Vanilla's routing table.
- Create a single prefix-list statement to filter out all subnets in the 126.96.36.199 range which has less than 256 IP addresses.
- Change your prefix-list so that only the default-route is allowed, as a result only the default route should be in Vanilla's routing table.
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 BGP, filtering, prefix-lists, route-maps and more.
