Back at Cisco Live 2013, there was some chatter around the Insieme deal and the potential to see a new switch from Cisco during the event. I think even Greg over at EtherealMind was hoping for some more juicy Insieme announcements at Cisco Live as well ( see post – http://etherealmind.com/musing-predicting-what-insieme-might-announce-at-cisco-live/ )Well, what we actuall got at Cisco Live was the Nexus 7700 switch and the Gold Cisco 6608 Catalyst Switches, not the hoped for Insieme switch.
Then today I saw that there an article posted over on NetworkWorld ( http://www.networkworld.com/news/2013/100213-interop-cisco-insieme-274455.html ) in regards to the Insieme Nexus 9K and Hardware Defined Networking that caught my attention. There is another article there – http://www.networkworld.com/community/blog/cisco-nexus-9000-aimed-40g – that has some output from a 9508 switch as well.

Ok, not new information by kinda new information to share.
Back in June during Cisco Live Orlando 2013 during the session BRKARC-2003 – Cisco ASR9000 System Architecture there where some slides that discussed a couple new ASR9000 series routers, the ASR9904 and ASR9912.
The ASR9904 is supposed to be released in October ’13, and that happens to also coincide with the rumored IOS-XR 5.1 release of code. Well, to date only the ASR9912 has been announced ( http://www.cisco.com/en/US/products/ps13288/index.html ), but with the recent release of the IOS-XR 5.1 Release Notes on Cisco’s website, the ASR9904 is listed there as can be seen in a snippet from that file: ( the original pdf release notes can be found here http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r5.1/general/release/notes/reln_510a9k.pdf )

VASI – VRF Aware Service Interfaces, what the heck are those?!
Cisco has defined a VASI interface as:
VASI is implemented using virtual interfaces that provide the framework necessary to configure a firewall and NAT between VRF instances. Each interface pair is associated with two different VRF instances. The two virtual interfaces, called vasileft and vasiright, in a pair are logically wired back-to-back and are completely symmetrical. Each interface has an index. The association of the pairing is done automatically based on the two interface indexes such that vasileft automatically gets paired to vasiright.
So you could look at a VASI interface as like a back-to-back connection between VRFs – call it a virtual cable of sort. You can also see that the traditional use of a VASI interface is to connect two VRFs, on the same router, together so they can route and NAT between each other. But what I am saying about Global Route Leaking?
Well, recently I had a problem where a client wanted to leak routes, dynamically, from a VRF to the Global table on an ASR1000 with an RP1 installed. We could easily have done it via a physical cable, but I knew their had to be a better way. I did some digging on the VASI interface and possible configurations and came across this – added in IOS XE 3.10S code is the ability to actually BGP peer over the VASI interfaces to exchange routes.
