    Selling 1500 INE Tokens

    I'm selling 1500 tokens for $.35 per token. 500 Tokens = $175 1000 Tokens = $350 1500 Tokens = $525 Let me know if you are interested

    IPv6 address confusion

    I think I see the confusion. Lets look at the IPv6 address a::e/126, the full address without any short hands is as follows: 000a:0000:0000:0000:0000:0000:0000:000e Breaking down the last portion ('000e') into binary: 0000 0000 0000 1110 The bold is the portion that is the network portion, and the last two bits is the host portion. When we convert the the IPv6 address into the shorthand ('::'), it does NOT include the first two bits of the hexadecimal value 'e' or 1110 in binary, meaning the left most two bits does NOT have to be all zeroes. Therefore, in order for the two routers to be consider part of the same network they have to fall into one of these ranges: a::/126 - a::3/126 00 00 - 0 00 01 - 1 00 10 - 2 00 11 - 3 a::4/126 - a::7/126 01 00 - 4 01 01 - 5 01 10 - 6 01 11 - 7 a::8/126 - a::b/126 10 00 - 8 10 01 - 9 10 10 - A 10 11 - B a::c/126 - a::f/126 11 00 - C 11 01 - D 11 10 - E 11 11 - F Hope this is clear and answers your question.

    OSPF over Frame-Relay – Part 1: Non-Broadcast

    The "Inactive" status relates to the other end of the PVC. Verify your frame-relay mapping on R2 and that the interface is up.

    " ip summary-address rip", why?

    I'm assuming you are talking about RIPv1. The RIPv1 doesn't pass the subnet mask in its advertisements, and therefore assumes the subnet mask of any local interface that is in the same major network as the received update. For example, if the router receives an update, and has a configured interface of, then the router assumes that is also a /24. If the router does not have an interface in the same major network as the update, then the major network subnet mask is assumed (/8) in the previous example. Since RIPv1 does not pass the subnet mask in its update, it doesn't support manual summarization (ip summary-address rip command) and auto-summary cannot be disabled. RIPv2 on the hand, does carry the subnet mask in its updates and therefore supports manual summaration and the turning off of auto summary.

    ip icmp error-interval command

    From how I'm reading it, one token is added to the bucket every 1000ms, and each ICMP error consumes one token. If 4000ms pass without an ICMP error, then four ICMP errors can be sent at a time for the next interval.

    question about cisco access server and securecrt

    I don't think you can setup multiple sessions over the console port. With my AS2511, I use ethernet to setup multiple tabs/sessions, and telnet into the access server using the port assigned to each device.

    Message Waiting Indicator Issue

    We've had this problem on occasion with our 7.1.3 system. I usually just uncheck/apply and recheck/apply the MWI for the user in unity and they don't have the problem anymore.

    BGP Adjacency

    By default when BGP begins to peer with another router, it will source the IP address of the outgoing interface. In this case, R2 will be using the S0/1 interface to reach R1 which has an IP address Since R1 doesn't have a neighbor command for this IP address (, it will refuse the connection. You could tell R2 to source the E0/0 interface with the command 'neighbor update-source E0/0', and the peer session between the routers should be established.

    Any guidance for CCIE R&S Labs

    I can't give a lot advice since I'm still pretty early in my Lab study, but I'll describe what I'm doing. Currently, I'm following a variation of the plan described in the following article: http://blog.ine.com/2010/10/09/how-to-pass-the-ccie-rs-with-ines-4-0-training-program/ The plan has you doing one Volume 2 lab most weeks, with you hammering out the problem areas from the lab with the volume 1 labs and other resources. I'm keeping a general long term schedule for 12 months. I'm hoping to shave a couple months off this schedule, but I'm not going to kill myself over it. I've been planning out a week at a time describing exactly what videos, chapters, and labs I want to go over each day. I'm devoting about 3 hours a day on weekdays, and 6 hours a day on weekends for a total of 27 hours. The scheduling allows me to keep track of how much progress I'm doing and helps keep me on track. Hope this gives you some ideas.

    New labs

    Very wise words.

    CCIE R&S Written Passed

    Your list look pretty solid. With Routing TCP/IP Volume 2, I would skip the IPv6 since its pretty dated. Volume 1 does a pretty decent job covering IPv6 especially paired with the Cert Guide and Cisco Docs. I've read Internet Routing Architectures when I was doing my BGP exam as my second source, and didn't really like the structure of the book. All the theory is in the first set of chapters with all of the configuration toward the end of the book. With that being said, IRA is a fairly small read (as far as technical books go) and does get into some very good examples that Routing TCP/IP volume 2 doesn't cover or at least not in as much detail. Routing TCP/IP Volume 2 also does a very decent job of covering BGP as well and should be enough for the written. Developing IP Multicast Networks was on my to read list, but I just didn't get around to it. Depending on how I do with the Cisco 360 labs in this department I may actually pick it back up. LAN Switching is old, and I just couldn't get past the CatOS commands which is why I used my BCMSN book for switching.

    CCIE R&S Written Passed

    The other chapters isn't covered by the R&S. For the R&S you mainly just need to know how LDP works, MPLS over Frame Relay, and MPLS VPNs. These chapters were actually recommended by Narbik in a post I found a while back (don't have the link). Chapter 5 is about MPLS over ATM, Chapters 8-15 cover Traffic Engineering, AToM, IPv6, etc. All of these topics are better suited for the Service Provider exam.

    When is your CCIE Lab date?

    When you go to actually pay for you exam it shows up as $1500. Strange that they didn't make any official announcements though, or at a minimum update the Lab exam information.

    My current setup is: 6x2811 1x2621xm (BB1) 2x3640 (BB2 & BB3) 2x3550 1x3560 1x2610xm (Frame Relay) 1x2511 (Access Server) I plan on getting a couple more 3560s to give me 4x3560s in the next few months.

    Thanks guys. I just scheduled my lab for Feb 20 in San Jose. My plan for the lab right now is to go through Narbik's workbook again for the next few months while I finish building my rack. I have a total of four weeks off between October and January, so I'll be doing the Cisco 360 labs during that time and on the weekends. I'll fill in the rest of the time with Narbik labs and the Cisco Docs. I think my biggest hurdle is learning to study properly. Well, good luck to everyone.
