L2L traffic multiple spokes routing

I have an issue that I'm hoping you can shed some light on this. I have 3 sites all connected with VPN/IPsec ikev2 tunnels using ASA 5505 and 5510 with 8.4+ code. Please see the image below for more details on my setup. All VPN tunnels are up and sending traffic across from the immediate neighbor, the issue is that I cannot ping or access ASA3's subnet from ASA2's or ASA2's subnet from ASA3's, what am I missing from my configuration? Please see below, and thank you in advance for any assistance you can provide with this.

  • Is it possible to have 2 DMVPN tunnels on a spoke router having 2 ISPs to the same hub?

    I have a router R1 acting as a hub for DMVPN. I have a spoke router R2 which has 2 ISPs. Can I establish a DMVPN tunnel via each ISPs to R1 from R2?

    the other posters are correct all you need is osx lion. i have tried it out and it works.
    the bottom line and most important thing to remember about multiple users using the same mac is:
    each user needs their seperate account. for example, if bob is on the screen, and tim logs on using vnc
    then tim gets his own desktop and kbd and mouse. but if bob is on the screen and bob logs on using vnc
    then they share the same desktop
    so if u want say 2 or 5 users or whatever the limit is, and i don't know. you are going to need 2 or 5 or whatever
    seperate users
    on the host mac you go into system preferences, sharing, screen sharing, and turn it on
    and on the remote mac you run finder, click on connect to server and type vnc:// and the address to the computer
    like vnc://192.168.1.4 and it should work great over the local network
    theres no other hardware or software you need, you just need to be running osx lion
    there is also vnc clients available you can download that might be better then the vnc client in finder

  • Load balancing using multiple default routes

    Hi Guys,
    I just want to ask does creating multiple default routes on my router provides load-balancing on my WAN side? As far as i know, for example if I have two default routes on my router and let say I have two users connecting to the internet, the first one might go to the first WAN link while the second user might go to the second WAN link.
    Thank you so much
    Rex

    there are the difference between, load balancing and load sharing..which we need to understand.
    load sharing means you have 2 users, user A and User B, user A wants to use ISP1 and user B wants to use ISP2. this is called load sharing. and can be achieved via PBR (Policy based routing).
    we should not try to use load balancing for Internet traffic with 2 different ISPs.

  • DMVPN split tunnling issue, not able to by pass http traffic at spoke end.

    Dear all,
    I would appreciate please help me out to resolve following issue.
    I have been using DMVPN setup (Routing protocol EIGRP) for 20 site no issue at all and everything is perfectly working.
    Now I received one request that I would need to split corporate legitimate traffic and internet traffic at spoke end, so all internet traffic has to forward via local ADSL connection , but I tried to resolve it but  spoke router is  continuously forwarding all traffic to tunnel.
    Moreover I found on internet that DMVPN has limitation that split tunneling is not possible.
    Please can you suggest me how can I forward internet traffic (HTTP) via local ADSL connection
    thanks and regards,

    I agree with Marcin.
    At the spoke you would need to add a static default route for the internet traffic.  You are also, most likely, injecting a default route into the EIGRP process at the hub, but the static route at the spokes will override this as it has a lower metric.  Depending on your setup, if the ADSL line is on a different interface than that of the DMVPN you could leave the EIGRP default route and use it as a backup incase the ADSL goes down.  But if they are both located off the same interface then there is no point in keeping the injected default route.
    Please remember to rate and select a correct answer

  • FlexVPN Spoke-to-Spoke Routing Override Loop

    I have a Spoke Router, this Router hat a Routing to inside192.168.1.0 255.255.255.0 next hop is 10.1.1.1(10.1.1.0/29 is the tranfer network):

    After active the FlexVPN i get the Routing override, then the routing is 192.168.1.0 255.255.255.0 tunnel0 in the Soke-Router. I lost the right routing, and i get the loop from Center to 192.168.1.0.
    How can i let the Spoke Router to ignore the Routing from himself from Center?

    One was would be to increase distance of routes received from hub.

    Dear All,
                This is my first time to write something .
                             i have configure DM-VPN, and it's working fine, now i want to configure static nat.
    some people will think why need static nat if it's working fine.
    let me tell you why i need. what is my plan.
    i have HUB with 3 spoke. some time i go out side of my office and not able to access my spoke computer by Terminal Services. because its by dynamic ip address.  so what i think i'll give one Static NAT on my HUB Router that if any one or Me Hit the Real/Public IP address of my HUB WAN Interface from any other Remote location so redirect this quiry to my Terminal Service computer which located in spoke network.
    will for that i try but fail. 
    will again the suggestion will come. why not to use .. Easy VPN. well sound great. but then i have to keep my notebook with me.
    i'll also do it but now i need that how to do Static NAT. like for normal Router i am doing which is not part of VPN.
    ip nat inside source static tcp 192.168.1.10 3389 interface Dialer1 3389
    but this time  this command is not working, because the ip address which i mention it's related HUB Network not Spoke
    spose spoke Network: 192.168.2.0/24
    and i want on HUB Router:
    ip nat inside source static tcp 192.168.2.10 3389 interface Dialer1 3389
    i am using Cisco -- 887 and 877 ADSL Router.

  • ASA as l2l terminaison point and route between remote peers

    Hi dear support community,
    I need to setup the following scenario :
    I managed to create the tunnels from routers to ASA but there are 2 issues :
    From remote LANs i am not able to ping the inside interface, apart if i use the management-access command on my inside interface, thing that i dont want.
    Remote LANs cannot communicate with each other. Is there some routing i should add ? My Inside Interface has a temporary permit icmp any any, and i guess that the ASA should bring up the appropriate routes when tunnels comes up. I have identfyed the routes correctly in my Crypto map and on my remote routers.
    As my remote routers all have dynamic assigned IP adresses they all fall into the defaultl2l Tunnel group. Is this wrong ?
    Any ideas or suggestions would be extremely appreciated

  • How to create production version for multiple BOM & Routing ?

    If I have 3 BOMs ( A, B & C ) and 2 Routing ( 1 & 2 ) for material XYZ then how then production version will be created ? I feel that there will be 6 PVs.
    combination of A1, A2, B1, B2, C1 & C2. but some one told me that  I have to create duplicate routing of 1 & 2
    with number 3 & 4 and use it for bom B, and another duplicate Routing with number 5&6 and use it for BOM C.
    in this case my PV data will be like this A1, A2, B3, B4, C5, C6.
    Please guide me which way is correct. I feel that the first way is right, because in that case I have 2 routing in system, and in second way I have total 6 routings for that product. please guide me.

    Hi Archana
      If you are doing component allocation with routing ,
    routing for material 1  counter 1 you are choosing alternate Bom  1 or 2 for material.
    similarly for Material 1 counter 2 you are choosing alternate Bom 1 0r 2 according to your choice
    like this   3 routing groups will get created with each have 2 counters
    if you allocate similar kind of material in one group in material allocation tab & you are going for component allocation it will assign one material bom.
    second material bom will not get assigned to the operation.
    if you are not going assign the component at the routing level than you can follow first process.
    if you are planning to allocate components at routing level than you have to follow second process.
    If have any more doubt kindly revert back with your query.
    Thanks & Regards

  • Response Groups - Duplicate "Built In" Services - Multiple Default Routing Endpoints

    Hello,
    I have a Lync 2013 deployment that has been migrated from OCS 2007, to OCS 2007 R2, to Lync 2010, and now to Lync 2013. I am including that information as that may be important for the following discussion.
    When the Response Group Service starts, it logs four error messages which I will place at the bottom of this post. The error messages point to duplicate routing endpoints for the same service. Upon review, it appears to me that I have duplicates of the following
    two services, when I look up the below SIP addresses with Get-CSApplicationEndpoint.
    Announcement Service
    RGS Presence Watcher
    My guess is that during one of these migrations, we ended up with a duplicate service. The problem is - how do I get rid of the duplicate, and how do I know which is the duplicate and which I want to keep? Error messages below.

  • Can I create a multiple waypoint route in Maps?

    I would like to be able to define my own route in the Maps App instead of picking from one of the 3 offered.  Is there any way that I can force a route to go through a specific location?

    Hi HAMADART and welcome to our community
    I'm a bit fuzzy on what you are looking for.
    If you are asking if you can create a hyperlink from a text
    caption that will open a URL or something, the answer is that you
    can, but not like you think. You would insert a caption and place
    it, then insert a click box object and program it to point to the
    URL. Then place the click box object over where you want your user
    to click.
    If you are asking if you can create a link that forces the
    Closed Captioning to display, first off I'd wonder why a link when
    clicking the CC button is so easy. But if you are asking if there
    is a way to cause Closed Captioning to display without user
    intervention, you need to take a look at fellow Adobe Community
    Expert Paul Dewhurst's site and use one of his widgets.

  • Is it possible to plot a multiple stop route in Maps?

    Does anyone know how to plot multiple stops on one trip?

    Nishan,
    The ability to show two x-axis criteria is limited and might be achieved if you can establish two metrics.  If you can get two (or more) metrics established, then fiddling with the "vertical iine and bar chart" capability may be the answer, however, vert line & bar only works with a minimum of two metrics present....  If you want two lines, then you can change the background of the chart to white and set the bar to white with no lines, thus they'll be "non-existent" to the human eye and only the lines will show through. 
    Thanks,
