Routed access OSPF design

Hi All,
I need some advise on the following design.
I am designing a campus network using routed access with OSPF. I will have 3 tiers - core, distribution and access. I am looking to configure the core/distribution links in OSPF area 0 and then the distribution/access links in a non-backbone area such as 1. I will then be able to filter/summarize etc as the ABR boundary.
I only have 2 links from my core to distribution layer and I'm planning to terminate them on separate distribution switches (dist1 and dist2), see attached diagram.
The links facing the DC will be in area0 and the links facing the access will be area1 but what area should the distribution to distribution link be in? I understand that if it is in the non-backbone area1 then I will loose the ability to use the link to the second core as intra area routes will be preferred by dist1. Are there any other considerations here? Should I connect two links between the the 4500s and configure 1 link in area 0 and 1 link in area1?
Thanks,

About how many L3 routing devices, and how many subnets, do you anticipate?  Depending on that, you might one to consider a single area design.

  • 802.1x Guest Vlan and Routed access layer design

    Hi!
    For many reasons, I have to re-design my campus network in a more ISP like way. The plan is to move to a routed access layer in the next two years. I have 802.1x with guest vlan on my access ports(3750). I was reading on the subject and I found that the guest vlan feature was not availeble with internal vlan(routed port).
    Is this limitation realy there, is there a way I can get around it without complicating my design even more. Do cisco have plan to lift this???

    You cannot use/configure 802.1X on a routed port today. Typically, 802.1X is to be used for LAN edge ports.
    The Guest-VLAN should work with a routed access design though. If your Guest-VLAN is chosen to be separate from say otherwise statically configured access VLANs, you would need to configure it via separate SVI with corresponding IP info (in a routed access model).
    Hope this helps,

  • Routed access design to support up to 2500 multicast groups

    Hi all,
    I'm doing routed access design with following:
    - Routing protocol is OSPF.
    - 3 layers with: Core/Distribution/Access design.
    - Core: Catalyst 6500E Sup 2T.
    - Distribution: ME 3800X / Catalyst 4500X.
    - Access: ME 3400E.
    We enable PIM from Core to Access layer.
    At the moment, there are around 1000 multicast group in the network.
    Cisco hardware limitation of multicast:
    - Cisco ME 3400E can only support up to 1000 IGMP groups and multicast routes.
    - Cisco ME 3800X can only support up to 2000 IGMP group and multicast routes with Metro IP Services license.
    - Cisco Catalyst 4500X support up to 32K multicast routes.
    - Cisco Catalyst 6500E Sup 2T support up to 128K multicast routes.
    Requirement:
    Design the network to support up to 2500 multicast groups.
    So, are there any fine-tune in the design to meet above requirement?
    Or I have to change access layer switch to higher model? (ex: 4500E)
    Thanks,

    hi there
    replacing the hardware is one option
    but the question here why are you going with routed access layer and in your case you have large Mcast routing table  that going to be everywhere !!
    have you considered using Cat65k or 45K in the distribution in VSS and use L2 from access to distribution
    in this case you need to concern about the distribution routing table size and also VSS simplify the topology and managerially of the network rather than have it with a complicated routing design
    routed access is a good and recommend as well for quicker convergence time and no reliance on STP or HSRP/VRRP timers
    however it could comlicate the routing design !
    while VSS will also eliminate the reliance on HSRP/VRRP and STP with more added simplicity to the topology and design
    so you may go with 45K VSS in the distribution and 65K with VSS in the core as well and in the access using L2 uplinks to the distribution and the uplinks everywhere can use multi-chassis etherchannel MEC, for increased network capacity in terms of bandwidth and quicker convergence time in the case of a link failure as well, Plus you will be able to support the desired Mcast routing table in the distribution and Core !!
    hope this help

  • How do I access LiveCycle Designer from my Adobe Acrobat X Pro?

         I am unable to access LifeCycle ES2 from my Adobe Acrobat X pro, even though I am supposed to have it as part of the software.  I have tried Forms/Edit forms, and I have looked for it through all the menus.  Several of the helps I have found for other things has me launch LifeCycle and operate from screens that LifeCycle designer provides. 
        I am using Windows XP professional.
        I would appreciate all the help I can get on this. 
    Thanks

    This worked!   I had to go into the system and launch it from the Designer
    9.0 folder, but thanks to your instructions I now have use of it.

    How do I access LiveCycle Designer from my Adobe

    Re: How do I access LiveCycle Designer from my Adobe Acrobat X Pro?
    created by TundraSteve in LiveCycle Designer - View the full discussion
    There is a terminology issue here.  From Acrobat Pro X you launch Designer
    not LiveCycle ES2.  LiveCycle is a server product.
    When you install Acrobat you have the option to install or not install
    Designer.  Look in the folder C:\Program Files (x86)\Adobe\Acrobat 10.0
    and check to see if there is a Designer 9.0 folder.  When in Acrobat you
    should be able to create a new form and it will prompt if you want to use
    Designer.  If all else fails you can always go into the Designer 9.0
    folder and launch FormDesigner.exe

    Any suggestion.
    I am able to telnet my server ip with port 6400 and 8080.
    Thanks

    I think there is some problem because of firewalls.
    Could some one tell me what are the list of ports need to be opned for server client model.
    i asked network team to open the ports 6400 -6410 only.
    Do i need to open ports ??
    My BO server installation is default and CMS is on - 6400. and i haven't configured anything else.
    pls suggest the approach.

    Hi,
    we participate the Early Adopter Program and work with AIA EAP 3.0. I think you mean AIA 11g!? The EBO Designer will be not a part of AIA 11g and will release later. May be somebody from Oracle can get a statement.

  • Using a Report Filter without giving users access to "Design" mode

    I have a report in which I use the filter bar to provide my end users the ability to use a drop down menu to switch between different months worth of data.  However, I have been asked to disable the ability for users to access the Design mode.  I have been unable to come up with the right security settings to allow the report filter while disabling the Design mode.  Does anyone have any suggestions to this problem?

  • Filtering External Type 1 routes between OSPF areas

    Hello. I have a situation where I have two different telco's providing Metro Ethernet services to my site. Both providers will be sending me routes as OSPF external type 1's. I want to prevent the ISP's routers from peering with one another. One way I was thinking of accomplishing this is by making the connection to ISP1 under OSPF area 1 and to ISP2 area 2.
    Is there a way I can filter the LSA's so no information is transferred between the two ISP routers in the two areas? Specifically, I don't want the type 5 LSA's generated by each ISP router to be sent to the other ISP router.
    Thanks

    Mike
    I do not think that configuring two areas will do what you need. But I think that you could achieve this by configuring separate OSPF processes. When you have separate processes they do not share information automatically. You must redistribute routes from one process to another and you can control what routes are redistributed.
    Finding the optimum solution would require more knowledge of your environment and your complete requirements than we have. But I syspect that something like this will work for you:
    configure ospf 1 and put the connection from ISP 1 into it. configure ospf 2 and put the connection from ISP 2 into it. configure ospf 99 (or whatever number you like) and put the connections from your network into that process. Then you can redistribute from 1 and 2 into 99 but not redistribute between 1 and 2. And if you need to advertise your routes to the ISPs then you probably need to redistribute from 99 into 1 and 2.

    Rick is correct, but if his response, with mine, causes any confusion. . .
    To OP's original question:
    If equal cost routes exist, OSPF uses CEF load balancing?
    The answer is technically no, for the reason Rick describes.
    But if we rephrase, such as:
    Does CEF load balance across multiple equal cost routes generated by OSPF?
    The answer would be yes.
    I suspect the latter question is what the OP really had in mind, but again, Rick is correct to distinguish that OSPF doesn't use CEF.

  • How to verify multiple paths available to a route in OSPF

    Hello,
    How do I verify multiple paths available to a route in OSPF
    I have three paths available to a route. I can see two equal cost paths shown in the routing table. The third higher metric path doesn't show up in the routing table
    When I disable the two equal cost paths, the third path is visible in the routing table
    Is there a command in ospf or shortest path algorithm, which can show the total number of paths available to a route and why one route is chosen over other
    Thanks,
    Chandru

    Thanks for the reply Reza. Is there a way to find all paths available in the ospf database.
    I just wanted to know the total number of paths available to an route in ospf area

  • Data Access Service Designer

    Hi,

    Hi Lutz,
    it is being quite long time since you created this thread. I came across it since I'm also interesting in Data Access Services.
    It seems that Data Access Service Designer is web based tool running most likely on JAVA Stack of BW server.
    I've found ABAP Class called CL_RSDAS_WDAPP which seems to serve as this web app starter.
    URL which thsi class triggers should be like:

    Can cisco router support OSPF-TE and ISIS-TE same time for CSPF to compute a TE LSP? I may need to run both IGP in parallel.

    Hi Johnny,
    Per my understanding you can. It is equivalent to running 2 IGP and installing the entry in RIB table based on administrative distance.
