    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 10.2.2.0, and has a configured interface of 10.1.1.0/24, then the router assumes that 10.2.2.0 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 23.0.0.2. Since R1 doesn't have a neighbor command for this IP address (23.0.0.2), it will refuse the connection. You could tell R2 to source the E0/0 interface with the command 'neighbor 13.0.0.1 update-source E0/0', and the peer session between the routers should be established.

    CCIE R&S Written Passed

    Passed with a score of 991. I've been studying for the written (and lab) off and on for about 2 and half years. Books I've read to prepare: CCIE Official Exam Certification Guide v4.0 CCIE Quick Reference Guide Routing TCP/IP Volume I & 2 MPLS Fundamentals (Chapters 1-4, and 6-7) Cisco QoS Exam Certification Guide 2nd Edition Cisco BCMSN Official Exam Guide Cisco Documentation (In particular the security guides, the design guides, IPv6, 3560 Switching Guide, and the network services) Workbooks: Narbik Advanced Technology Workbook I've read all all of these books multiple times over the past few years, and will probably will do so again before I do the lab in February/March. Even though my journey isn't over yet, I would definitely like to thank Darby and others for the advice they've given on this forums.

    GNS3 + Breakout Switch

    I plan on buying a few switch and want to hook GNS3 up to a breakout switch. Since trunking is required between the PC and the switch, I was wondering if anyone knew of any usb ethernet adapters that support vlan tagging? My onboard NIC is a Atheros ar8131 which does support configuring a VLAN ID, but I can't seem to find any utility to support tagging. Any help would be appreciated. Thanks

    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.

    CCIE R&S Written Passed

    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.

    Backbone Router Advice

    Narbik's workbook uses IPv6 on both the BB1 & BB2 and all of the switches. I haven't actually done these lab, just skimmed through them. The feature navigator for that 12.2T and 12.3 IOS images does show some support for IPv6, but I'm not sure if it is enough to complete these labs. I have a couple of 2610xm, and NM-2E2W are pretty cheap so I may go that route just to be safe. Thanks

    Backbone Router Advice

    Hi, I am studying for the CCIE R&S lab, and I am using the Narbik Advanced Technology workbook. I've looked through some other threads on this forum and see recommendations of using the Cisco 2505 for the backbone routers. Will I have any problems running all the labs on these routers, such as IPv6? I know the 3550s may also have some issues with IPv6, has anyone ran into any problems doing the IPv6 Narbik's labs on these switches? I'm also looking into a secondary workbook such as Cisco 360 or INE, any recommendations would be welcomed. My current setup is: 4x2811 2x3550 1x3560 1x2610xm w/ NM-8A/S (Frame Relay Switch) 1xAS2511 I am plan on buying two more 2811 and another 3560. Thanks

    narbik workbook

    I think Narbik's workbook is great for getting the technologies down. The tasks are fairly simple which means you can focus on learning the technology. I usually try to work out the task myself before looking through the solution. I've been coupling the workbook with the IPExpert VoD which have been working pretty well together. I wasn't a big fan of the volume one workbook by IPExpert due to what I feel was conflicting solutions to the task. As far as errors, I did notice quite a few errors the first time around, but their pretty quick at fixing mistakes in the workbooks.

    GNS3 + Breakout Switch

    I'm curious if anyone has gotten this to work on Windows 7? When I trunk between the v-switch and the real switch I can only communicate on vlan 1. I'm thinking that the network card I am using is stripping the vlan tags from the packets.
  22. Try giving Users modify access to the GNS3 folder.

    Theory and Approach to Written...

    Early this year, I was following the plan of pure theory, take the written, then start doing the labs. I've come to realize that, I wasn't getting the depth that I wanted. I ended up pushing my written back to later this year, and started doing the labs from the Narbik and IPexpert workbooks. I've recently started to revise my schedule once again, this time I'm going to go more in depth over each technology. As I cover each technology, I will do small labs with lots of debugs, show commands, and packet captures to prove how these technologies actually work as I read the theory. I will then do the technology-specific labs from the workbooks. I've been writing lots and lots of notes with diagrams of how things should work, and how things actually work (RIP holddown timer comes to mine). I plan on taking my written in 6 months, and 3 months after that the actual Lab. I'm hoping to get enough money for Narbik's bootcamp somewhere in the mix. I will be using mainly rack rentals and GNS3. I have a small lab of 6 routers and 2 3550s. I'm probably just going to sell the routers and buy a couple poweredge 1950 servers to run gns3 and buy some 3560s switches. For the theory I will be using the Routing TCP/IP books, DocCD, IPexpert videos/audios and RFCs.

    DTP Frames

    Sorry, I was refering to cdp being flooded only if L2 Protocol tunneling is enabled, which after doing some digging found out that it actually changes the well-known mac address to a cisco tunneling multicast address (01-00-0c-cd-cd-d0). Cisco switches know to absorb frames with destination address of 01-00-0C-CC-CC-CC. This is why PVST+ must use another multicast address (01-00-0C-CC-CC-CD) so that older Cisco switches, that don't support PVST+, don't absorb the multicast frames.

    DTP Frames

    Cisco switches will listen for the DTP multicast address and won't flood out the frame. Switches that do not support DTP will treat the multicast address like any other multicast address and forward it out all interface and could possibly cause misconfiguration on the network. So it therefore recommended to disable (switchport nonegotiate) on ports connected to third-party devices. Switches won't forward CDP multicast frames for the same reason, unless you turn off cdp on the switch.
