BGP Lab v01
by David Sudjiman ~ March 6th, 2008. Filed under: Cisco.
This is my BGP lab I’ve created on dynamips. I don’t have the time to explain in details why I configure it this way. This is actually part of my BGP/CCIP study. So, don’t expect you will find BGP/CCIE level on this lab.
This lab consists:
– Multihoming to multi ISP
– Usage of Weight, Local Preference, AS-Path, and MED.
– Multipath
– BGP dampening
– ORF
– Confederation
– Route-Reflector
– Next-Hop
– Aggregation
– Cluster
– and probably some more I could not remember.
Enjoy!
