INE’s long awaited CCIE Service Provider Advanced Technologies Class is now available! But first, congratulations to Tedhi Achdiana who just passed the CCIE Service Provider Lab Exam! Here’s what Tedhi had to say about his preparation:
Finally i passed my CCIE Service Provider Lab exam in Hongkong on Oct, 17 2011. I used your CCIE Service Provider Printed Materials Bundle. This product makes me deep understand how the Service Provider technology works, so it doesn`t matter when Cisco has changed the SP Blueprint. You just need to practise with IOS XR and finding similiar command in IOS platform.
Thanks to INE and keep good working !

CCIE#30949 – Service Provider
The CCIE Service Provider Advanced Technologies Class covers the newest CCIE SP Version 3.0 Blueprint, including the addition of IOS XR hardware. Class topics include Catalyst ME3400 switching, IS-IS, OSPF, BGP, MPLS Layer 3 VPNs (L3VPN), Inter-AS MPLS L3VPNs, IPv6 over MPLS with 6PE and 6VPE, AToM and VPLS based MPLS Layer 2 VPNs (L2VPN), MPLS Traffic Engineering, Service Provider Multicast, and Service Provider QoS. Understanding the topics covered in this class will ensure that students are ready to tackle the next step in their CCIE preparation, applying the technologies themselves with INE’s CCIE Service Provider Lab Workbook, and then finally taking and passing the CCIE Service Provider Lab Exam!
Streaming access is available for All Access Pass subscribers for as low as $65/month! Download access can be purchased here for $299. AAP members can additionally upgrade to the download version for $149.
Sample videos from class can be found after the break: Continue Reading

In our R&S CCIE Mock Lab 2 there is a BGP task that relates to having a particular router prefer an iBGP route as the preferred path to exit its local AS over an eBGP learned path. This seems like a very simple task and it is if you are very thorough with your verification but it ends up being the most commonly missed task in this particular mock lab. Lets start by going over the task and the solution most commonly implemented by students.
In the lab R1, R2 and SW2 are in AS 300. R1 and R2 each have an eBGP peering session with R3. The task states that AS 300 should use the T1 link between R1 and R3 to reach paths originating in AS 54 (BB3). R3 (sub-AS 65003) appears as AS 100 but is actually in a confederation with R4 (sub-AS 65004) and R5 (sub-AS 65005). This doesn’t have any bearing on the task but needs to be mentioned for clarification when looking at the diagram and the output of the show commands. Below is the full task and the diagram (click the image to enlarge).

I’m currently working on updating the Vol 2 Troubleshooting labs. I’m changing a good portion of the tickets and increasing the difficultly level of each lab. So if you’ve done the Vol 2 Troubleshooting labs in the past it’ll benefit you to go back through them. I’m also adding in a lot more layer 2, QoS, MPLS VPN and multicast related tickets. I hope to have this finished and uploaded sometime late next week or early the following week.
In addition to updating the Vol 2 Troubleshooting labs I’m currently working on a brand new Troubleshooting workbook for R&S. This one is based on a new rack topology that has 28 routers and 4 switches. Our new troubleshooting racks are being built now and we should start beta testing early next month. This workbook will support our new Troubleshooting racks, GNS3 and I even have a couple Cisco employees who are going to test the labs out for IOU support. Anyone who has our current workbook series will automatically receive the new Troubleshooting workbook free of charge.
I’ll be making another post later this month or early next month regarding additional updates and changes to our R&S workbooks. As always current customers will get the updated workbooks free of charge. Keep submitting any issues for our R&S workbooks using the feedback form in the members’s site. Weeks like this between teaching my brand new live R&S bootcamps I look through the reported issues to see if any updates are needed.
Over the coming weeks, you may notice blocks of racks being reserved as I’m having the 2600XMs removed and replaced with 2811s. The 2600XMs will replace the 2500s as the backbone routers. This will speed up the reload and rack reset times. The only changes you will see if that R1 and R2′s serial interfaces will now be S0/0/0 and S0/0/1 in contrast to S0/0 and S0/1. R1 and R2 will also have an additional Ethernet connection to SW1 and SW2 along with BB1 being connected by Ethernet to SW1 Fa0/24. These changes will not affect the current workbooks and our rack automation has already been updated to support the interface changes.
Our new CCNA and CCNP racks are being finished this week and should be available for rent after the recording of the CCNA and CCNP bootcamp videos this month.
Lastly we will be releasing new mock labs between November and the end of the year. These new mock labs will be based on a different physical rack topology than INE’s currently physical topology. I’ll post more information regarding them in the coming weeks.
If you have any specific questions regarding the R&S workbooks feel free to email me directly or post your comment below.
Good luck with your studies!

If anyone was wondering what they get for $300 when you add-on the printed option to the R&S CCIE Workbook bundle see the image below. Since I’m working on the updates, I ordered a printed set for myself. I’ve been working on the electronic versions and knew it was a lot of material but was surprised at the sheer amount of material it is when it’s all printed out and laid on the floor in front of you.

One of our most anticipated products of the year – INE’s CCIE Service Provider v3.0 Advanced Technologies Class – is now complete! The videos from class are in the final stages of post production and will be available for streaming and download access later this week. Download access can be purchased here for $299. Streaming access is available for All Access Pass subscribers for as low as $65/month! AAP members can additionally upgrade to the download version for $149.
At roughly 40 hours, the CCIE SPv3 ATC covers the newly released CCIE Service Provider version 3 blueprint, which includes the addition of IOS XR hardware. This class includes both technology lectures and hands on configuration, verification, and troubleshooting on both regular IOS and IOS XR. Class topics include Catalyst ME3400 switching, IS-IS, OSPF, BGP, MPLS Layer 3 VPNs (L3VPN), Inter-AS MPLS L3VPNs, IPv6 over MPLS with 6PE and 6VPE, AToM and VPLS based MPLS Layer 2 VPNs (L2VPN), MPLS Traffic Engineering, Service Provider Multicast, and Service Provider QoS.
Below you can see a sample video from the class, which covers IS-IS Route Leaking, and its implementation on IOS XR with the Routing Policy Language (RPL)

The BGP MED attribute, commonly referred to as the BGP metric, provides a means to convey to a neighboring Autonomous System (AS) a preferred entry point into the local AS. BGP MED is a non-transitive optional attribute and thus the receiving AS cannot propagate it across its AS borders. However, the receiving AS may reset the metric value upon receipt, if it so desires.
Previous versions of BGP (v2 and v3) defined this attribute as the inter-AS metric (INTER_AS_METRIC) but in BGPv4 it is defined as the multi-exit discriminator (MULTI_EXIT_DISC). The MED is an unsigned 32bit integer. The MED value can be any from 0 to 4,294,967,295 (2^32-1) with a lower value being preferred. Certain implementations of BGP will treat a path with a MED value of 4,294,967,295 as infinite and hence the path would be deemed unusable so the MED value will be reset to 4,294,967,294. This rewriting of the MED value could lead to inconsistencies, unintended path selections or even churn. I’ll do a follow up article on how BGP MED can possibly cause an endless convergence loop in certain topologies.
