Further discovery requests (e.g. ARP, ND) from other attached hosts could then all be directly replied, eliminating broadcast gratuitous arps. If the switches don't support the protocol they would default to flooding the discovery requests. It seems to me that so many network are caused because of the inability to change the host mechanisms. Sam It looks like in 2011 Cisco proposed a technology called OTV that would do just that, according to this page: http://network-101.blogspot.com/2011/03/otv-vs-vpls.html Granted, it was aimed for wide-area networking, rather than control within a datacenter; but as everyone who has started doing BGP to their top of rack switches has learned, there's often good value in adopting techniques and protocols used in the wide area network within the datacenter as well. However, I haven't heard recent mention of it, so I'm guessing it failed to make a big enough splash to get any widespread adoption. Also consider the emergence of eVPN and PBB-eVPN. https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=5998tclass=popup -- = bep smime.p7s Description: S/MIME Cryptographic Signature

question - is there any tracking about how much bittorrent traffic there is across the various ISP's
I am looking for numbers on the amount of BitTorrent traffic flowing around the Internet today. Any idea where I could find both numbers of events and bytes used info? Todd -- Thanks, Todd S.

Re: 2000::/6
hey, Any decent router won't allow you to enter just anything in that range into the export rules with a /6, except 2000:: itself, and will even show you a failure response instead of silently ignoring the invalid input, for the very purpose of helping you avoid such errors. IOS was already brought up, luckily Junos and TIMOS do just that (both for prefix-lists and static routes). Unfortunately directly connected networks remain and there is no way to solve that. -- tarko
QSFP 40G breakout cable
Hi folks, Anyone from the northern VA area has a couple extra of these? I'd like to borrow for a couple days to see if they work in other vendors' equipment? Believe it or not, Cisco' s one is much cheaper. Thanks! rg/lmn
