    Multilink on 3600 Series not working correctly

    I assume that the input errors on 0/1, 1/0, and 1/1 are incrementing (ie they're not historical) ? You can use the 'clear counters' command on the router and re-check the interfaces after 15 mins or so to verify this. If the errors are incrementing then this is the issue I'd focus on. If the...

    PacketLife CCNP Study Notes

    This is (unfortunatly) going to be bedtime reading for me.... sitting an exam tomorrow following a 6 month BSCI course (prior to sitting the Cisco cert). Feeling like the facts are falling out of my head faster than they are coming in.... Thanks for the post.

    Layer 3 Redundancy in a /30 Subnet

    Thanks for the star. You should also be aware that HSRP may only be one half of the equation. HSRP can fail over the routing 'out' from your LAN, but you may also need to consider managing the data flow in from your ISP should one of your routers fail. For example, if the A-leg router fails...

    Layer 3 Redundancy in a /30 Subnet

    We run HSRP for our clients and (even with redundant links) they all have a /30 range on the WAN interface of the routers. The HSRP config usually sits on the customer LAN range, so that the HSRP IP, physical IP's etc are all taken from the customer IP address space, rather than the /30 WAN...

    Bottleneck on 1721 over 1Mb

    You appear to have a Virgin Media Cable Modem. Is the Cisco 1721 router being assigned a public IP addres or a private IP address ?

    CCNP Route Redistribution

    Hi Lerdalt, Thanks for responding. I understand that as RIP v1 is classful it would only 'want to see' a 128.103.35.0/24 route, but I'm not grasping why the longer subnet mask on OSPF size of the network (/28) stops the GW-2 router from redistributing the route into RIP alltogether ? The...

    CCNP Route Redistribution

    Hi All, Attempting the CCNP Academy course and I've hit a section I'm just not grasping. I can understand what the course is saying, but not WHY. If I don't understand the reasoning behind it, I feel I wont be able to apply it. Section 5.2.3 Redistributing Routes from Classless to Classful...

    Reverse Telnet on a 2511 ?

    Hello all. I've just spent the morning trying to set up reverse telnet from a Cisco 2511 to devices in a home lab (Cisco switches and routers). I have a single Octal cable currently connected to 'ASYNC 1-8', but the furthest I've managed to get is: Terminal#telnet test3 Trying test3...

    Recommendations for a CCNP Lab ?

    Thanks for the great link CiscoGuy. Read the blog end to end and signed up to the newsletter. Exactly what I was looking for (and more).

    Recommendations for a CCNP Lab ?

    Hi All, I'm about to re-certify my CCNA, prior to commencing a BSCI course and was wondering if anyone could recommend a list of switches and routers to make up an approriate CCNP lab ? I have some existing equipment (Cisco 2500's, a 2620, 2621, 3620 and a 2950 XL switch), but suspect that...

    Updating IOS

    Hi, IOS's are available via the Cisco site, but are not necessarily free. If you don't have an existing support contract or access to an existing account with IOS access privilages then you may need to pay a fee to upgrade. It's also a good idea to register at the Cisco site to gain access...

    Purchased used 3640 router, having rommon problems

    Hi, Looking at the initial error messages it looks as if the 3640 has entered rommon as it has been unable to load an IOS image (cannot read flash info). After failing to read the onboard flash memory, it looks as if it's checked the 2 PCMCIA slots on the 3640 to see if these are populated...

    Determine Memory Modules Installed via CLI ?

    OK - found out how to do this for the 3620 - any offers (assuming this is possible) for the 2620/2621 ? How to Determine the SIMM Configuration of a Cisco 3620 or 3640 Series Router http://www.cisco.com/en/US/products/hw/routers/ps274/products_tech_note09186a0080104555.shtml

    Determine Memory Modules Installed via CLI ?

    Hi, A seemingly simple problem, that I've been unable to resolve. I've just put together a CCNP lab and am now trying to determine how much, and what combination, of DRAM memory is installed in each router (2620, 2621, 3620). I realise that a 'sh ver' command will give me the total DRAM...

    CCNP Lab ?

    Hi All, Passed my CCNA recently and am now considering starting a CCNP (proably the Advanced routing / BSCI first). Anyone have any suggestions about what would be a suitable mix of kit to purchase to allow me to complete the majority of the CCNP labs ? I know there are sims available, but...

    Forwarding port 80 with NAT on cisco 2611

    Apologies - just re-read the posting and realised I misunderstood what you were trying to achieve.

    Forwarding port 80 with NAT on cisco 2611

    I've no real experience of configuring NAT, but it looks as if the NAT translation is configured correctly to overload to the dynamic IP obtained by e0/0 for any client in the 10.1.1.0 range. However, given that the 10.1.1.0 range has already been mapped to overload to e0/0, it may be that...
