Your autonomous system has a lot of IBGP routers. You are already familiar with route reflectors which saves you a lot of trouble configuring all the IBGP neighbor peerings. You just read about BGP peer groups which sounds very interesting. Less CPU overhead and even less configuration for you. Let’s see if this will work
- All IP addresses have been preconfigured for you as specified in the topology picture.
- Configure a peer group called “PEERS” on router Bit.
- Router Byte, Octet and Nibble should only form IBGP peerings with router Bit.
- Ensure you have full connectivity within AS 1234.
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 and more.
Does this sound interesting to you? Take a look here and let me show you how to Master CCNP ROUTE
Configuration FilesYou need to register to download the GNS3 topology file. (Registration is free!)
Once you are logged in you will find the configuration files right here.
To have full connectivity, ensure that you configure the loopback addresses on all routers. the Most important point here you need to add “redistribute connected” under BGP on Bit router.
Otherwise the iBGP client(s) will have the loobacks on the BGP table but “NOT” the routing table.
Cheers Mate !!!
Great quick, easy lab to get hands on with Peer-Groups and iBGP.
