Opinions expressed here and in any corresponding comments are the personal opinions of the original authors, not those of Cisco. Dear readers, The first recommendation I would like to highlight prior to go deeper through the different articles is, don’t extend the layer 2 segment beyond your physical DC if you don’t need. Keep in mind that for a better cost containment while maintaining easier IT operation, it exists different solutions to geographically (cold) migrate an application, while maintaining the same platform identifiers without extending the LAN across long distances – e.g. LISP IP mobility across subnet mode. . – Do I really need to extend my subnet outside my data center ?
– Can Layer 3 help to support application mobility between sites without LAN extension ? – When and how can we optimize the traffic to and from outside the DC or between application tiers after a move of a machine.

Posted by Brenon Daly on September 9, 2015 Contact: Brenon Daly In both August 2015 and August 2011, concerns about slowing global economies knocked stock markets around the world into a tailspin, while also ratcheting up volatility.
Intuitively, we would assume that both conditions, which introduce more variance and uncertainty, would make it more difficult to do deals. But is that actually the case? And if so, what can the whipsawing markets from four years ago tell us about how M&A activity might play out for the rest of 2015? To get a sense, we split 2011 into a ‘pre-turmoil’ period of January through August, and then a ‘post-turmoil’ period of September through December (which is roughly the same four-month block that remains in 2015).
Through the first eight months of 2011, dealmakers averaged $22.3bn in spending on tech, media and telecom (TMT) transactions each month. We have noted how the black swans have already befouled the M&A market in the short term. Virtual insanity. Tech Field Day - The Independent IT Influencer Event. Revolution Wi-Fi.

Juniper devices are quite flexible when it comes to routing tables and exporting prefixes between them, but all rib groups mechanism is not well explained in documentation.
In general Juniper documentation is not really good but well….
