Dmvpn with Redundancy

I am setting up a backup dmvpn. 
What is the best approach to this design whiile using eigrp
one tunnel with load balance or two tunnels while changing the metric on the SPOKES

Hi,
You can refer the below mentioned document to find a best fit solution for your redundant model.

  • Problem with redundancy in CSS 11051

    I have a problem with redundancy in CSS 11051. I use firewall load balancing and server load balancing. Load balancers which only load balance over 3 firewall switch from primary to master with no problems.
    problem is with load balancers which load balance over firewalls and over servers two. whene the master is shutdown, backup keeps master function, all services on backup LB are alive, but it is not possible to display web page on address 10.10.7.16. Even if I try from the network 10.10.7.0/24, so before firewalls. below my config. any help appreciate.

  • Two servers with redundant connections for Sun StorEdge 3320 SCSI arrays

    Hello All,
    I read in the "Sun StorEdge 3000 Family Installation, Operation and Service Manual" that it's possible to setup "two servers with redundant connections" but I never see a detailed schema to do this. I read also the "Best Pratices Guide" but this case is not mentioned. Is it really possible ?
    My objective is to split a Sun StoreEdge 3320 SCSI array between two hosts with dual redundant scsi connection.
    Thanks in advance for your answers.
    Francois.

    At first this sounded easy, but looking at the parts listing for the 3320 seems to indicate otherwise. They're listing different part numbers for the chassis and midplane...
    371-0105 chassis & midplane for JBOD
    371-0106 chassis & midplane for RAID array
    There are also different part numbers for the I/O boards....
    370-7655 RAID SCSI I/O module
    370-7713 JBOD SCSI I/O module
    I can see what the difference is between the I/O modules, but am unsure of what differences if any are in the chassis and midplane. Seems like there's more involved here than what it would be worth to try and make it work. Perhaps the cost of a second HBA would be the lesser of two evils..........

  • Not clear with the statement ( A large double value with redundant D )

    Hi,
    I am not clear about the statment below. What does redundant D means.
    *123.4E+306D// A large double value with redundant D*

    By default any floating-point literal in Java is a double, so the trailing D that specifies that explicitly is redundant.

  • Nexus 5596 reloads with redundant PS after 1 PS breaks down

    Hi All,
    We have a Nexus N5K-C5596UP with redundant power supply. 2 x N55-PAC-1100W.
    Last week 1 of those PS broke down. When this happened the chassis reloaded. I wouldn't expect this to happen.
    Does anyone have an idea of why this happened?
    Our NX-OS version is n5000-uk9.5.2.1.N1.1a.

  • IPSec for Redundant DMVPN with VRF

    Hi.
    I have been labbing up a solution using DMVPN and VRF, similar to that described in the blog post here.  It works very well, however when I try to extend the concept to a redundant hub, it breaks with IPSec.  If I remove the tunnel protection, it works fine.
    Does anyone have any ideas about providing IPSec protection to multiple DMVPN tunnels for VRFs to a redundant Hub?
    Thanks.

    Under the Hub you have to add
    HUB1
    interface Tunnel10
    ip nhrp map 10.254.254.1
    ip nhrp map multicast < ip add of FastEthernet0/0 for HUB2>
    HUB2
    interface Tunnel10
    ip nhrp map 10.254.254.3
    ip nhrp map multicast < ip add of FastEthernet0/0 for HUB1>
    The same thing for the other tunnel interfaces

  • Guest web redirect with redundant ISE

      Dears,
    I have redundant ISE configured (primary and secondary) and integrated cisco WLC 5508.
    I already configured SSID for Guest Web authentication.
    With primary ISE the redirect link is working fine but when I power off the primary ISE the redirect link stop working even if I changed the Role of the secondary to primary.
    Please I need your support,
    Regards,                

    Thank you for your reply,
    - Yes on the same nodegroup.
    - Yes resolved correctly in the DNS.
    - I will recheck it but I already create an ACL for redirect.
    - Yes the both ISE defined on the Radius Auth. on the WLC.
    Now I will check the ACL and back to you.

  • 10g ports with redundancy

    Hi all. I hope this is the right section to post this kind of question.
    Basically I need to know which switch should I buy to achieve the customer's needs.
    Each floor will have 1 x 2960 with 2 10GB uplink to the core switch. The problem is I don't know which switch should I buy acting as a CORE. The customer needs at least 16 x 10G ports for each switch and the core must be redundant in some way. So the 3750 is not an option and I thought about the 4500-x with VSS but actually I'm not sure this is the best idea. Servers will be attached directly to the core switch (I know, this is not the best idea but this is what the customer want to do).
    Thanks for you replies / help

    Yes, VSS with the 4500-X is one possibility, as would be the new 6880.
    Or, instead of VSS, you could use a 4500, 6500 or 6807 with dual sups and dual line cards.
    With VSS, your single point of failure is the IOS.  With the (redundant card) chassis, your single point of failure is the chassis, itself.  There's not much of a difference in MTBF.
    Any of the above (or Nexus) would likely work well for you.  Selection depends on your budget and feature requirements.

  • Dual cloud dual hub single tier dmvpn with backup service provider

    Hi,
    I have a design issue with a WAN network. I have decided to use dual cloud dual hub single tier DMVPN topology (ref. to http://www.cisco.com/application/pdf/en/us/guest/netsol/ns171/c649/ccmigration_09186a008075ea98.pdf - "Dynamic Multipoint VPN (DMVPN) Design Guide"). I have tested in lab 2 hubs and 3 spokes, applying the mentioned technology. Everything is OK, when the primary hub fails, there is only 1-3 seconds loss (3 pings).
    The problem is that each spoke and hub will have 2 service providers for WAN - primary and backup. I am still wondering which design is better and more stable to implement - using more DMVPN clouds (for the backup service provider network) or creating static IPSEC GRE tunnels in the backup links?
    Is there a guide for this case?
    What is the best practice in this case?
    Thanks in advance,
    Mladen

    Dynamic spoke-to-spoke requires your spoke routers to have mGRE tunnel interfaces. If you ever have a spoke which sources 2 tunnels from the same physical interface, you have a problem: how to resolve which tunnel is an incoming NHRP request for?
    My DMVPN is a bit different in that the crypto is GETVPN on the physical interface. There is a crypto-map applied to the physical interface and it has 2 entries which correspond to the GETVPN crypto-groups for each tunnel.
    I resolved this issue by making one of the 2 tunnels on each spoke router mGRE and the 2nd one point to point. the mGRE tunnel is preferred as primary (we use eBGP through the tunnel, so routes received through the mGRE tunnel are local-pref'd high and we AS path prepend routes advertised out the point-to-point tunnel)
    I haven't gone back and tested what happens when you have a spoke which has 2 tunnels sourced from the same interface and another spoke with 2 tunnels sourced from the same interface or from 2 different physical interfaces. The concern is that you may get a situation where one router uses Tunnel 2 for dynamic spoke-to-spoke tunneling, and the other uses Tunnel1, and that the dynamic tunnel setup fails because the crypto map cannot properly decide which crypto group to use for the incoming traffic on the router where 2 tunnels use the same physical interface.

  • DHCP loadsharing with redundant Guest Anchor Controllers

    Hi
    I have 2 x Redundant Guest Anchor Controllers (5508) located in 2 separate Data Centres with all the management and guest user VLAN spanned between two. Everything is working fine with the Guest WiFi access except the DHCP functionality as the Controllers are acting themselves as the internal DHCP Servers.
    This is how I tried to distribute
    network. 10.1.0.0/23
    gateway: 10.1.1.254
    Controller 1, DHCP Server pool: 10.1.0.2 - 10.1.0.254 Gw: 10.1.1.254
    Controller 2, DHCP Server pool: 10.1.1.2 - 10.1.1.254 Gw: 10.1.1.254
    As the user loadbalancing between the Anchor Controllers cannot be controlled (i.e. they are active/active), the same client sometime getting 2 different IP addresses from both the Controllers (as they do not talk to each other in terms of DHCP) hence depleting the pool addresses.
    I guess one way of solving this is to just run 1 DHCP server in one of the controllers but that defeats the purpose of having N+1 Controllers. Is there a better way of doing the DHCP loadbalancing and having full redundancy at the same time?
    Any suggestion will be greatly appreciated.
    Regards

    Thanks Scott, I understand that it's quite obvious to get an external DHCP Server, unfortunately it's not an option for us The weired thing is, it seems when a client joins the guest WiFi, both the Anchor Controllers (both functioning as DHCP servers with mutually exclusive IP Address space) are providing IP addresses. While the client accepts only one the other Controller still reserves the IP address unused and hence depleting the DHCP Pool.
    I thought for load balancing (in the very beginning) the Foreign controller will forward the DHCP request to only one of tthe Anchor Controllers, but in reality it's forwarding it to both. I have tested this with only one test AP, so mobility doesn't seem to be an issue here. Any thoughts?

  • Metro Ethernet Design With Redundant Head Ends

    We're getting ready to turn up some metro ethernet circuits that were just installed by AT&T. AT&T has provided a VLAN for each remote site (so each site has its own VLAN), and those VLANs are trunked to our head end switches (Cisco 3750 Metro Switches).
    I'm struggling with the best design for IP routing. We currently use OSPF on our internal network, and I was going to extend OSPF to our metro solution as well, but I'm not so sure now.
    I don't want routing to occur directly between head end #1 and head end #2, we already have redundant paths within our corporate network, and allowing our two head ends to route between each other via our metro ethernet solution is not what we want. However, running OSPF on each of the VLANs which have been provisioned for us would permit routing between the head ends.
    We simply need to allow redundanny for our remote locations in the event that one head end were to fail, all of the traffic to/from the remote site would be routed through the head end which is still online.
    Anyone suggestions on the best routing design for this situation would be greatly appreciated. I've attached a network diagram to make things clear. I believe I can also go back to AT&T and request one VLAN that includes all sites if that would simply things. I just need to make sure I can still do our traffic shaping because the remote sites are only 10mbps and the head ends are 1gbps.
    Thanks,
    -Steve

    just at a glance it looks as if you should be able to have stp on and setup 1 site as primary and other as secondary

  • Spatial object with redundant geographic coordinates

    Hi,
    in my spatial table there are many entries with the same geographic coordinates (latitude and longitude). They are different sites with different site information. As I do a spatial query using MapViewer API method queryWithinRectangle(), the results of the sites with the same geographic coordinates can not be all retrieved or all rendered in the map. Has anybody met the same problems?
    Best regards

    Thank you for your reply. I have used the methods you suggested all the time. I have not declared my problem clearly in the last post. I need to retrieve the geometries and render them in the map. On the other hand, I need to retrieve the non-spatial attributes and diplay them in a list. The problems I met are that the both retrieval result sets are not identical. I guess, the redundant spatial information in the database leads to this disagreement. For example, in my spatial table two different rows have the same spatial information (latitude and longitude). My question are whether somebody knows this problem and what is the solution?

  • DMVPN with 270 spokes

    Hi
    We have a DMVPN network with about 270 spokes (831) and 2 hubs (3825). We run EIGRP in all branch of the network.
    We had experience many problems so far, but one of them seems to be related with the amount of traffic that is generated when some of our hub went down for about 15 to 30 seconds. All of our spokes start blinking on EIGRP but our VPN still up. Here is some of our messages that we have on Hub side (peer goodbye receive, stuck in active, hold timer expire). Our EIGRP timer are 5/15 but we tried 60/180, but we had the same issue.
    We have a fiber 5Mb on one hub and the other hub have 10Mb fiber link.
    Does anyone heard someting about that ?
    Thank your very much for your help.

    This problem may happen because of various reasons like one of the neighbors reseting the other due to routes stuck in active, some router reporting a k-value mismatch, etc. Following links may help you

  • MPLS issues with redundant PE routers

    Hello,
    i'd like to set up an mpls lab. the layout of the gear is attached (mpls.jpg) At site A i have to PE router R4 and R6 which should have knowledge of the network 10.0.129.0/24 from site B. Router R1 is configured as a route reflector. the configuration of R1, R4, R5 and R6 are attached as well.

    any ideas what i have to do in order to have a redundant path towards site B?
    thanks in advanced
    Alex

    Hi Alex,
    I think you still have redundancy via R6, but BGP route on R6 is not getting installed in routing table because it is having OSPF route with lesser AD value. If R4 goes down, R6 will loose OSPF route for 10.0.129.0/24 coming from R4, install BGP route ,redistribute this to OSPF and will advertise it to SW4.

  • ASA Active/Active Failover with Redundant Guest Anchors

    Does anyone know how an ASA and a guest anchor 5508 will interact if I setup an Active/Active failover pair with physical interface redundancy?  I see from documentation that I can create a logical group in the ASA to bond physical interfaces together, but it doesn't describe what protocol is being used to manage that bundle.  Do I assume etherchannel?  If I were to create this scenario, can I run the 5508 in LAG mode?
    The current failover configuration example is for PIX, and old code at that.  I'm referencing an ASA/PIX guide ISBN:1-58705-819-7 beginning on page 531.
    Regards,
    Scott

    In addition to what you have, you should add to each unit the global configuration command "failover".
    We generally don't manually configure the MAC addresses in single context mode since the ASA ill automatically assign virtual MAC addresses and manage their moving to the newly active unit in the event of a failover event. Reference.
