3.7.d Implement optimize and troubleshoot routing policies

3.7.d [iv] Communities, extended communities

one can never thank this guy enough… he has 51 bgp labs alone available for download, free and ready to configure… he also has many others that cover most of ccie… one of the nice things about his labs is they tend to concentrate on a particular subject…

i have been going through all of them as you can see… and beginning to make a dent…

i have 16 more of his bgp’s left…

i also scrape the task lists and include them into the corresponding folder so i don’t have to go digging into his site to get the tasks when i do them again… of course i bitch about the names of the routers all the time, i would prefer just r1, r2 etc, but that’s a tiny complaint in the entire scheme of things… so again, thank you rene… it is a wonderful thing you’ve done for us fellow sufferers…

the value of this is incalculable…

if you have been living under a rock you haven’t noticed that i have been spending quite a bit of time on bgp communities this week… whether or not the enterprise network can get the cooperation of the isp to effect the usage of communities is immaterial… one of the ancillary benefits of using communities well is the improvement you will find overall in how you manipulate bgp…

this is a very instructive lab… if you are smart you will not save the configurations while you build them; next time, you have ip addresses only as if it was the first time…
