I did InternetworkExpert.com mock lab #6 today. I really have no idea how I did. I didn’t have time to check much of anything. I did as many checks along the way as I could, but I never did an end-to-end reachability check (if you can believe it). I attempted nearly every task, ...]

“encaps failed on broadcast for link 38″ =’s No IP Routing I come to find out. IP Routing was shut off on R1 which killed me lol. I couldn’t find anything on this error when setting up the frame-relay connection between R1 and R2 Friday night. The worst part is I thought it was a hardware ...]

Private VLAN concepts are quite simple, but Cisco’s implemenation and configuration steps are a bit confusing - with all the “mappings” and “associations” stuff. Here comes a short overview of how private VLANs work. To begin with, let’s look at the concept of VLAN as a broadcast domain. What Private VLANs (PVANs) do, is split the ...]
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.

Cisco IOS has a special feature called local policy routing, which permits to apply a route-map to local (router-generated) traffic. The first way we can use this feature is to re-circulate local traffic (and force it re-enter the router). Here’s an example. By default, locally-generated packets are not inspected by outgoing access-lists. This may cause ...]
