Cisco’s way of confirming LSUs
I think i’m addicted to GS, since in those 6 or so hours that it was down, i started to get real nervous and basically display all symptoms of addiction. Nervous walking from side to side, checking my email every 2 minutes even though I know it’s going to be updated automatically, searching through archives…
But anyway, on to my question. It is about Cisco’s implementation of OSPF. As all of us know, there are two ways to acknowledge an LSU. Implicit: by sending the exact same copy of the LSU Explicit: by sending summary of LSU in LSAck.
Now, I understand what the standard is and how it is supposed to work. What I am asking is if any one knows what Cisco implementation uses. Sniffer results that I got from GSR show that it send only LSUs, but never LSAcks.
It’s all up to standard, but why not use LSAcks? Or does it only relate to GSR platform?
