L2 and L3 Routed Link between 2 COREs

Hi
What is the difference between L2 (Dot1q) and L3 Routed Link between 2 COREs in term of Functionality 
thanks

Hello Ibrahim ,
I will try to explain , 
VLANs put tag on frames to ensure packet do not leave layer 2 broadcast domain and yet will reach to all ports part of that vlan ( as per tag ) .
Layer 3 SVIs on other hand provides layer 3 reachability for vlans and hosts inside layer 2 vlan . To achieve this all layer2 vlan host provide with related layer 3 SVIs ip address as gateway .
I hope you got it by now .

  • Sockets and ports - routing messages between machines? helpppp!

    Hi,
    I'm new to java and am hoping someone out there can help me, hoping this is an ok place to post this:
    If all you need to create a connection is an IP address and a port number, using streams...
    Can you route messages from A to B then from B to C, where A looks up C through B having a hash table which contains C's IP address and port number?
    And how in the first instance does B know about A's IP address? All the examples I've seen the IP address is hard coded?
    Thanks in advance!

    I'm not sure what you are really trying to do... Can you explain in more concrete terms? Are you writing a chat client + server or something like that?

  • Loaded Forms on the screen and the underline link between the forms-Callee

    Hi Dear Experts,
    I am wondering wehter you would be able to shed some lights on the follwoing and on how SAP handles below situations:
    In SAP when loading up two documnts and try to add items to each using 'List of Items' screen, the systme is clever enough to return back the item code to the relevant screen.
    I need to know that how SAP is holding this trail of formids when returning the select item code to fill in the document lines on the origianl caller doc.
    Is it some kind of  internal array structures or it could be a table in the database which contains the list of loaded forms on the screen and the revelant callee and caller ids.
    Many thanks in advance.

  • Is there a DIRECT link between SD schedule lines and delivery lines?

    Is there a direct link (db table) between schedule lines on a sales order (VBEP) and the delivery lines (LIPS)? 
    Is there a function module to retrieve the data?
    Example-
    One order line with 3 schedule lines.
    Each schedule line is for 2 units (total of 6 units).
    Three deliveries made.  1st is for 2 units, 2nd is for 1 unit (backorder), 3rd is for 3 units.
    You can use document flow (table VBFA) or examine the SD document in the delivery line (LIPS) and link the delivery line to the order line.  The schedule line already references the order line.
    I am using math to decrement the schedule lines used and make the link between VBEP and LIPS.  It works fine.  I need four records back....
    1st schedule line for 2 units uses delivery 123
    2nd schedule line for 1 unit (partial) uses delivery 124
    2nd schedule line for 1 unit (partial) uses delivery 125
    3rd schedule line for 2 units uses delivery 125
    Like I said, it works. Just wondering if I missed a more direct link.

    As far as Db link is concern , I don’t remember exactly , but 3 years before I had written a report which see Sales order schedule lines and devilry note lines against sales order.  If you see process wise…. when ever you create PO ( production order you assign some qty using 101 movement type .. and against production order you also give sales order . When you do delivery ( run seclude run ) it delivers against that material number , its movement is 601 ...
    but I remember there’s a link between these tables, VBAP,VBFA AND VBEP , LIPS ...  against every sales order you can see sales invoice ( VBRP,VBRK) and you can also see your delivery note number in document flow .
    I hope this’ll give you some guide line, as right now I can not tell you the exact business process but I remember I written a report in SD 4 years before , in which they required Delivery against production order and sales order ... One more thing you also have production order reference on delivery item number. ( field :Empst ) . I think in my project they were maintaining this field .
    Thanks

  • Link between Cost element GL Account and WBS element.

    Hi,
    I want to get the List of all dollars sitting on the GL account  attached to the selected WBS element.
    For this, Any one please suggest me the table where i can get the link between the WBS element and GL account.
    or
    Table for link between the Cost element and GL account
    and Table for link between the Cost element and WBS element.
    Thanks,
    Suresh.

    Hi,
    1. There is no link between cost element and WBS
    2. Link between cost element and G/L account is one-to-one. This means, that if it's a primary cost element it has the same code as the G/L account. If it's a secondary element, no link exists.
    3. The table where you can see the postings on your WBS is COEP. There you will find the cost element, WBS, amounts, etc.

  • Direct link between planned/production order & Stock transport order

    Hello,
    We have the following situation.
    Plant A = ordering/receiving plant
    Plant B = producing/selling plant
    Material is stock material in plant A (reorder point planning). If required, plant A creates intercompany purchase order with plant B as vendor.
    Standard SAP behaviour: MRP run will create planned order in plant B but there is no direct link between the intercompany purchase order and the planned order. It can as well be that this planned order combines several requirements.
    Our requirement: Have a 1 to 1 relationship (and a direct link) between the intercompany purchase order and the planned order (and also with the production order which will be generated afterwards). The solution we think about: After creation of the purchase order, create firmed planned order (or immediately production order) by means of a bapi.
    My question is whether there are standard SAP solutions for this?
    Best regards
    Kurt

    When customer give order and then it creates sales order.
    depends on material - I mean Finshed good or Comapny own product ,
    If it is outside material ,it creates Purchase req and then Purchase order.
    if it is company material ,it creates Planned order and then production order.
    Check the transaction you will get better idea.

  • Failed to retrieve data from the database/invalid argument provided when employing link between two web services datasources

    Post Author: vpost
    CA Forum: Data Connectivity and SQL
    I am trying to join information from two related web services within CR XI. I have successfully set up the web services as data sources have been able to get to the point where I get good data back. However, when I try to pull in certain fields, I get an error that says "Failed to retrieve data from the database/invalid argument provided". Here's the scenario:
    The web services are structured as follows:Web Service 1 (Artist) has attributes of Artist Name and Date of Birth.Web Service 2 (CD) has attributes of CD Title and Release Date. Underneath each CD are songs, each of which have a Song Title and Artist Name.
    I have defined both web services and defined a link between Artist.Artist Name and CD/Song.Artist Name. I am able to run a report with Song Title and Date of Birth that crosses web services. I am able to run another report with Song Title and CD Title that crosses the different levels in the second web service. However, if I add CD Title to the first report or Date of Birth to the second (both of which effectively force CR to employ the link between the two web services AND the CD/Song hierarchical structure in the second web service, I get the aforementioned error.
    Any assistance understanding how multiple web services can be linked in this manner would be greatly appreciated.
    Thanks in advance.

    Not sure about your exact situation, but having similar problem with another application and have tracked down to security. Added user to group Domain Admin and it works fine. It appears to be accessing a subdirectory which it does not have permission to use and then times out and returns the "invalid....". Seems that once the query just over a certain size (and I'm not sure what triggers this) it needs to make use of temparory file disk, intead of ram.
    I'm still trying to track down which temporary it's trying to uses - so if you have any ques.

  • Technical link between a PM order and its operations (routing number)

    Hi all,
    I would like to know how to make link between a PM order and its routing number for operations in the order (field AUFPL) ?
    Thank you.
    Regards.
    Laurent.

    Hi again,
    I just found function module CO_DB_HEADER_READ.
    With Order Number as import parameter you got in export parameter CAUFWA value AUFPL.
    Then with +AFV+* tables, you have operations data.

  • Establishing Link between Order and Routing

    Hi
    When I am creating an order (e.g. production order from CO01) by default itu2019s getting Routing and BOM. I want to know from where my order is populating BOM and Routing?
    I want to know how the link between Order and BOM and Order and Routing are established
    Thanks

    If you want to see how the tables are linked you can see this in table CAUFV (order header).  Fields PLNTY, PLNNR, & PLNAL define the task list type, group, and group counter.  These can be used to look up the routing information in tables PLKO and PLPO.  The BOM link is in field STLTY, STLST, & STLNR (bom category, status, and BOM).  Use these values to find the the BOM details in tables STKO and STPO.
    If you want to know how the system knows which BOM and routing to bring in, that is done in configuration under Order plant dependent parameters (t-code OPL8).  Also, once the boms and routings are copied into the order you can make changes to the operations and components within the order.  The operation and component details that are stored in the order can be found in tables AFVC and RESB.
    thanks,

  • Cannot Establish Gigabit Link Between Catalyst Switches and GSR Router

    The GSR Gigabit interface is configured for no negotiation auto and the line protocol goes up when connected to the Catalyst switch.
    The Catalyst switch port remains unconnected even when it is physically attached to the GSR router.

    The flow control settings must match on both sides for the link to come up. It is highly recommended that you configure auto-negotiation to on for both devices. (Auto-negotiation is enabled by default on all Catalyst switches.) Otherwise, if you have a layer 1 problem, the link remains up and a unidirectional link will result.
    The initial software releases that support Gigabit Ethernet on the GSR router do not support gigabit auto-negotiation.
    The following command configures gigabit auto-negotiation on the Catalyst 6000/6500:
    set port negotiation module/port disable|enable

  • Redundant Transparant ASA between Redundant Routed Links

    Aparently the Security/Compliance team didn't review my network design before it was submitted and built, and now I have to shoe horn a firewall somewhere there was never supposed to be one.
    I have my two current DC Cores (Nexus 5548UP), that currently are Layer 3 only, with no L2 configuration at all.  I understand these aren't the best switches for this role, but the BoM was put in place and gear ordered, long before I came onboard, and the DC design had been completed.  From these two Cores, i connect directly to a vendor's clustered Fortinet FW, via a /30 from each core to each node of their cluster, and connected via eBGP, one link with a path prepend, due to the vendor not able to figure out how to load balance on their firewall.  Due to numerous vendor problems, and lack of knowlege, I cannot get them to change their design in a timely manner, to meet our timelines, and this has to be up yesterday to be PCI compliant (so our security people say) prior to go live in 1 week.  The vendor took 3 weeks just to figure out how to aggregate routes to me!.
    So I want to drop a transparent pair of firewalls inline on the two links, but due to the Active/Standby limitation of ASA's, I am not sure this will be that easy given the /30 L3 interfaces being used.  Secondly the lack of L2 between the two upstream cores may be a concern, at least from past expiriences.  I know if I was using some other vendor's clustered FW, this wouldn't be a problem, but I definately don't want to join the Dark side again, or do I have time to procure any other equipment other than the 5520's I currently have laying around.  Someone please tell me I have overlooked something simple, and the design listed below will be simple to implement!!!!
    Any ideas appreciated!

    why you don't use this design:
    connect the vendor clustered direct to nexus with a vrf instance, then route traffic to asa and then route to nexus whith other vrf istance.

  • Routing issue between Cisco device and Virtual machine

    Hi Guys,
    We have two local subnets in a virtualized environment, subnet 1 has a VM operating as a firewall, we would like all traffic for subnet 2 to go via VM on subnet 1, this will police traffic on subnet 2 and then reroute.  
    The infrastructure involved comprises,
    Internet Edge Switch -> ASA -> Core Switch -> IBM Flex chassis
    The Internet edge switch is directly connected between the ISP routers and the Cisco ASA firewall pair (A/S). The ASA is then connected to the Core switch. Connected from the core switch is an IBM Flex chassis, via a port channel (all vlans allowed)
    The local subnets in question are as follows:
    Vlan 101 (10.1.1.0/24)
    Vlan 102 (10.2.1.0/24)
    The VM in question has two NIC cards having IP address of both subnets.
    NIC 1:  10.1.1.1
    NIC 2: 10.2.1.1
    We would like packets destined for 10.2.1.1 to land on 10.1.1.1 IP address. At the moment traffic for each vlan routes from the outside to their respective local subnets successfully, what we are having difficulty with is directing traffic for subnet 2 via subnet 1 VM firewall.
    At the moment we have tried adding a static route on the core switch but it didn’t work
    ip route 10.2.0.0 255.255.255.0 10.1.1.1
    I will appreciate if you could share your knowledge and guide me how to achieve this goal.
    Thanks in advance :-)

    Hi,
    I think for this to work you need a transit vlan between the VMs and the core switch. So, if you have 2 vlans on the VM (101 and 102) you use the VM switch to route between the vlans and in order to go outside the local vlans you would use the core switch.  In this scenario you would not have an SVI (layer-3) interface on the core.  The only thing that core will have is the layer-2 vlans (101 and102).  You would than need a static route on the core switch to point to the transit vlan on the VM side.
    so, for example, if the transit vlan is vlan 110 and the ip is 192.168.1.0/24
    on the core you have static routes:
    ip route 10.1.1.0/24 192.168.1.2 (VM side)
    ip route 10.1.2.0/24 192.168.1.2 (VM side)
    You also need an SVI for vlan 110 with ip address 192.168.1.1/24 on the core.
    on the VM you need a default route to point to the core (192.168.1.1).
    Is this what you are trying to do?

  • My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

    My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

    Thanks for your response
    Let me give the history - I started with an Apple Express being fed thru a D-Link  EBTR 2310 cable Router from an RCA DCM315 Modem (Pure). Comcast service all the way.
    Got the 1st generation TC in 2008 and merely replaced the Airport Express with the TC. Worked ok
    A year or two ago I did try removing the modem and feeding the TC directly from the modem. Resulted in the same condition I have now - Continuous flashing amber on the TC. So I put the router back in the chain.
    Some time later, at the recommendation of a Comcast rep, I replaced the router with (a Belkin F5D 5231) to see if speed and dropout problems would be improved. I thought it helped some at the time but now I am not so sure.
    Last week I decided to see if a new modem would help with download speeds. So I got another pure cable modem (Motorola SB 6121- high on the Comcast recommended list).
    Got up and running easily with Comcast help and with the modem connected directly to a computer.
    Next I put the TC in the link and again could not get past the TC continuing to flash amber. Although I did get connected to the internet with this configuration I lost connection two both of my printers - one connected by USB and the other wirelessly to the TC. Again everything works fine when I put the Belkin router back in the system.
    However with the router in there, the modem shows the downstream connection to be 10/100 ethernet speed. (Modem light changes color for indicating speeds.}
    I have gone thru all of the combinations of powering down/ up, but all stays the same.
    I can live with what I have but something still doesn’t seem right.
    Thanks again
