I completed InternetworkExpert.com version 4.1 volume 3 labs 3 + 4 on Saturday. The IEWB volume 3 labs are supposed to make you faster at core tasks. These labs are what I consider “half-labs”. They cover PPP, frame, ethernet switching, RIP, OSPF, EIGRP, BGP, and redistribution. So far, so good. ...]

Let’s say you get a bunch of inexpensive (but a bit outdated) routers (36XX or 72Xx) and some really nice (maybe not so cheap) Cisco switches (e.g. 3550/3560) and you would like to provide a VPLS-like service to your customers. Since VPLS is a service available only on more powerful Cisco platforms, we have to ...]

You can use transcoding resources available on a separate chassis with CME. You can go upto 5 sdspfarm sessions. CME will share all available resources. CME configs: ip source-address 10.1.11.4 port 2000 ———– 10.1.11.4 is the CME router. sdspfarm units 2 sdspfarm transcode sessions 2 sdspfarm tag 1 mtp0013c3443150 —- this transcoder is on the same box as CME. Lets ...]
Once I learnt more and more about ccie virtual lab, I fostered a desire of writing on ccie virtual lab. Now that my desire has been fulfilled, I hope your desire for its information too has been fulfilled. #
span>Last but not least, i own an apology to my account team (how the hell did Cisco find my blog???), because as it proved out i was half-wrong regarding a "prediction" statement in my previous post:
I already know the answer from our account team. "Yes, you can do whatever you like with ASR1000". But i also know the answer from TAC : "Sorry, this cannot be done due to QFP".
Well, they actually said that we should first check the features we currently use on the 10000 and 7200 routers. Then check which ones are supported in the first release of IOS XE and when the rest of them will be available. After that we can see when (and if) we can test the ASR1000. Let's hope TAC will prove me wrong too ;)
Some days ago Cisco introduced the ASR1000 Router Series. A breakthrough in technology according to Cisco; something that will probably change the networking industry.
What does it have to do with the title?
The Good (QFP), the Bad (PXF) and the Ugly (SW)!!!
QFP is the QuantumFlow Processor, where ASR 1000 Series Embedded Service Processors (ESPs) are based on. PXF is the Parallel Express Forwarding and it's the where 10000's parallel multiprocessor architecture is based on. SW is just software (CPU) switching, something that 7200/NPE-G1 (and most other routers) is based on.
So let's start with the Bad...the PXF and the 10000:
When Cisco announced its 10000 Edge Services Router in 2000, it said:
The Cisco 10000 ESR is based on Cisco's revolutionary Parallel eXpress Forwarding (PXF) architecture. PXF utilizes Cisco's latest parallel-pipelined network processor to deliver wire speed performance for a broad set of Cisco IOS. advanced IP services. The combination of a rich IOS feature set and PXF performance enables ISPs to increase revenues by deploying value-added services such as Premium Internet Access to customers in volume. The highly-scalable router delivers maximum expandability to handle growing customer populations and expanded service offerings. In addition, the Cisco 10000 ESR and its breakthrough architecture have been designed for maximum reliability and availability to support customers' ever-increasing dependence on network-based services.

Jeremy has an excellent site I found today while reading a post on Cisco’s Subnet over on Network World. Packetlife is full of great matrerial for anyone trying to grasp the core topics for their CCIE or routing in general. Excellent PDF’s and posts on core material so far. Very education to say the least. ...]

Although the title sounds like spam, I’m not selling any pills here. Rather, “getting a performance boost” describes what I’m going to be working on in the next few weeks as my lab date approaches. I want my core configuration to be fast and flawless. The issues for me now are not understanding tech as ...]

Updates coming for all of the labs soon, been very busy at work, but have been making progress through the labs. I have now done the core section of Lab 10. I am hoping to get my updates done soon.
