Life

Some free time here in Europe and thus time for another quick blog post & to take my mind away from depressing people!

One of impressive features of major European networks is support for BGP communities. In India it’s almost non-existent. Setting it up isn’t hard technically but from capacity management side, Indian ISPs are somewhat shy in setting it up.

Let’s put a case where we have a Customer router (R1 with AS1), upstream of customer (R2 with AS2), upstream of upstream (R3 with AS3), peer of upstream (R4 with router4). Let’s try to setup communities so that customer at AS1 can control his BGP announcements and announce some prefixes to AS3 and some to AS4 selectively to control inbound traffic flow. 

It’s late evening here in Radaur and I am sitting in my room with open door looking outside in dark. I wonder if darkness outside is more then darkness I see in our system. No, I am not referring to any routing glitch or bandwidth chock point but even more fundamental issue that is “Lost sense of Engineering” in current education age. It’s pretty hot weather out in my room. I will start this blog post with two interesting real life experiences from last few years.
