BGP Peer Group
by Rene Molenaar 2 Comments
Scenario:
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
Goal:
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
