    Hi Rick. r u ok? .. it’s amazing that you can go fast to your great goal. i’m on the way that you are. i’m going to build my CCNP/CCIE home lab and prepare myself for the CCIE. but unlike you i have many problems in front of me that hope to solve all of them one by one. congratulations to you. i’m waiting to see your 3rd CCIE. I promise that you can have all of 6 CCIE as soon as possible. good luck.

    Mr. Mur,

    You are one focused individual and an inspiration to us all.

    When studying for your Cisco certs do you rent rack time or do you have a study lab or possibly both?

    I also wanted to get your opinion on the following:

    I want to know if you think my existing lab is adequate for CCNA study. If I need extra equipment I want to make sure that I can also use it for CCNP study as well.

    So here is what I got.

    1841 2FE, 2 T-1 Wics V2
    2620 1FE, 2 T-1 Wics V1
    2611 2E, 2 T-1 Wics V1
    2610 2E, 2 T-1 Wics V1

    2 2950 T Switches

    I was told that I can connect the routers via T-1 cross over cable. I have those on order. However I have been advised I will not be able to use my 1841 because the V1 and V2 Wics cannot be crossed in this fashion.

    Should I stick with what I got for now? Or would it make sense to get 2 more 2600XMs and toss the regular old 2600s?

    dear i have to choose between Cisco ASR9000 and Juniper MX480 for IPoE Session Termination with Radius CoA.
    Can give you opinion/feedback for about these device

    • rickmur


      I would definitely go for the MX480! The ASR9k is currently not ready for supporting high scale of IPoE sessions and they are working on getting the software there, but that takes until second half of next year.
      Juniper is currently far more up to speed with the features and with scaling figures. I also tested a high scalable virtual chassis cluster set-up without any issues. So my choice would definitely be an MX instead of ASR.
      Maybe by the end of next year this will be different, but NOW the MX has much more features (and they have a long-term-support release for it!)


      • Pns

        Hi Rick,

        Could you please advice a low end IPoe termination equipement.


        • rickmur

          Any CPE can do that. I’ve been using FritzBox, Zyxel and Huawei. This was all residential based. Otherwise use a SRX. (it’s basically any box that can do DHCP 😉

    Hi Rick,

    Everyone writes about BGP path manipulation using the standard attributes of bgp. Can you write a blog about how you can manipulate paths in a large ISP having ospf as igp. This is important because not always the Intra AS trafic takes the path but the path through bgp but through the igp since bgp next hop is reachable through igp.

  13. Serge

    Hi Rick,

    I guess you are very busy but I am interested in VXLAN. As far I understood, VXLAN configuration occurs on the Cisco 1000V (vswitch) and then IP multicast must be configured on upstream physical devices ?
    In fact, I work on the creation of a new data centre with cloud services.

    Thank you

  14. Shady Darwish

    Rick i need advice about wich track to go for CCIE R&S or Datacenter.Note that i covered 40% R&S 10% datacenter tracks and have support to attend any of both bootcamp by my company.

    Hi Rick. In your JNCIE-ENT lab, is there a particular reason you used two switches instead of just using one switch?

    Hi Rick, I just have one question. I am in my 4th(final) year of my Engineering degree program. Would you suggest me to rather go for CCIE data center right away along with my college from an institution or wait until I finish my degree and then start off preparing for CCIE from an institution ?

  27. Anu

    Hi Rick, so happy to come across your site. I am presently preparing for my CCIE R & S, i am just curious to ask the advantages of owning a personal ccie lab. I am presently working in a networking company, which is a select partner, as a result projects are only coming in bits not frequent. So i felt a need to have my own lab. please advice.

    Hi Jeffery,

    My name is Justina, and I work for Zocalo, a social agency on behalf of Dell. I wanted to share some information about an upcoming contest that you and your audience/followers might be interested in. We’re calling it the Ultimate Tech Challenge: Servers. Dell and Microsoft want to hear a particular challenge you’ve faced while dealing with servers and storage, and the unique and creative way you’ve solved the problem. The premise is simple – answer the following question based on an experience you’ve had on the job:

    How do you best use SSD as a storage option with Microsoft Windows Server for optimal performance and cost?

    Dell and Microsoft will select their favorite response from those received and turn it into a white paper that highlights the problem and unique solution utilized to solve it. The selected winner will also receive a Dell XPS 12, valued at $899.99! Entering is easy – share your challenge and solution in a blog post on your blog/site or your response to [email protected].

    Since you’re a Microsoft MVP, I’d really like to feature you in our white paper and share your expertise and name with others. We’ll be running a paid promotion campaign alongside the white paper across various platforms. Would you be interested in collaborating by answering the question above and being part of this white paper?

    Looking forward to hearing from you,

    Hi Rick,

    I need your expert advice. We have WiMax Network that has MSER SE1200 as BNG/B-RAS. This MSER acts as DHCP relay as well as PEF (Policy Enforcement Function of PCEF w/o charging) and we want to replace it with MX960 without major reconfiguration on our IP CORE/MPLS Network. What I mean is that, our MSER is connected to our PEs and subscriber circuit/clientless ip service (clips) are created via L3VPN. Our PE has L3 connection towards MSER. If possible, I can email to you the network diagram. Juniper vendor partner here in country informed me that we should create L2VPN or VPLS or Pseudowire for us to use MX960 as BNG. Is there any way without using L2VPN/VPLS/Pseudowire? Is it possible to use L3VPN?



  30. Jayagiri Nair

    Hi Rick

    I am preparing a jncie lab as you mentioned, bought 2 x EX4200 and 4 x SRX100H devices. Do you think that 4 x SRX100H is enough or do we need 2 more as you mentioned in your lab? Also SRX100H is still useful for everything (BGP Route Reflector practice) or do we need to think SRX240H as it has Gig connections which are important for the exams in anyway?

    Thank you for the time,
