Phase 3 of DMVPN. Two clouds on talk

• Address problem Source DMVPN Dual-Cloud

  Greetings,

  I run a pivot single double-cloud DMVPN in operation phase2 (talk-to-spoke active).  I am very surprised that the question does not come upwards more often.

  Here is my configuration:

  Each station has its own ISP.

  Each remote site has a single router connected to ISP (interface1 and interface2) 2

  Each head of public-IP network is routed static (/ 32) through a single interface.

  The default route is floating based on an IP SLA monitoring mechanism.

  Note the following image (showing the host routes) static and default

  

  With the two routes by default the value of the interface making DMVPN-X, a spoke-to-spoke on DMVPN-X works well.  But what of the talk-to-spoke out DMVPN?  It gets broken in the following way:

  At Site A, my TunnelY Interface come from 10.2.0.2.  After it to Site B; s public IP (10.4.0.2) via PNDH, he's trying to form a tunnel spoke to rays.  But how to get to 10.4.0.2?  It uses its default route on the 10.1.0.2 interface with address 10.2.0.2 source.    A few things can happen:

  (1) ISP blocks the bad sources completely, either explicitly or through uRPF.

  (2) talking-to-Spoke Tunnel arrives, but assymetic routing is performed (this is rare)

  (3) all sources of the ISP Nat to himself (gateways Comcast SMC this) in the example above, you see 10.1.0.1 crypto packages arriving at 10.4.0.2!  Imagine the confusion caused

  In most cases, isakmp is watered.  Even if the tunnel is in place, I don't want to assymetic shaping with all the bandwidth on a single interface - I like to use actively both ISP connections.

  Then... How to handle this?  I predicted it, but I thought that the mechanism of the PNDH/DMVPN would deal with this situation.  that is if I hear one speak via TunnelY and TunnelY is source on Interface2, it would naturally be to send packets on interface2.  Alas, this isn't the case.

  Here are some ways that I thought to solve:

  (1) because my end points are not dyamic, I could host statically road all rays are out all the interface2s, all the X on the interface1s.  (with 30 sites, it's so ugly, that I hesitate to even include it)

  (2) road map of each external interface and match against the source address.  If interface1 detects a source interface2, set-next-hop to interface2.  The same thing on interface2 - if she hears a source corresponding to the IP address of interface1, value jump following interface1.  It is repeatable, but looks a bit ugly as well.

  (3) poster on the forums of Cisco and see what the consensus is

  Thank you much in advance.  Here are my configs sites speaks if you need:

  Example of use of site A above:

  Route IP 1.1.1.1 255.255.255.255 10.1.0.1

  IP route 2.2.2.2 255.255.255.255 10.2.0.1

  IP route 0.0.0.0 0.0.0.0 10.1.0.1 Track1

  IP route 0.0.0.0 0.0.0.0 10.2.0.1 250 (for failover if track 1 breaks down)

  This is usually resolved by separating the ISP in before VRF (keeping global VRF inside if you chose to), allowing both titled tracks.

  It's late (almost 1:00) but I think that tunnel road-via could potentially work too.

• Can integrate us two cloud Planning Application?

  We can integrate the two clouds full of applications or any other method of planning score so that an application data can flow into another application.

  Two applications of SEEP tell you? No chance of partitions for security and performance reasons, you will need to extract the data and then load it in the other application, you can use the REST API or the EPM automate utility to automate the process.

  See you soon

• Policy of ITS phase 2 ISAKMP DMVPN is not acceptable!

  Hello world

  I'm having toruble with a DMVPN basic configuration. In debugging I can see how ends the phase 1 ISAKMP, but they phase 2 proposal fails. It says something about a cryptomap that does not exist. I thought that with these configuration I have needs not a cryptomap. The configuration of routers and print screen debugging are attached. Any help would be popular.

  Try this:

  Crypto ipsec transform-set average esp-3des esp-md5-hmac

  transport mode

  Also, since both the rays and the hub are behind a NAT NAT - T, you'll need, so certainly don't turn it off.

• New on DMVPN - internet Hub do talking

  Currently setting up spoke and DMVPN between a hub.  We use all static routing.  I managed to create the tunnel and I am able to get into our internal network by spoke them lan.  However, I am unable to get any internet access.

  This is the static routing on the RADIUS:

  IP route 0.0.0.0 0.0.0.0

  IP route 192.168.48.0 255.255.240.0

  In our old site 2 site scenario, simply recall the default route for the Tunnel interface and then traffic would flow like that and then statically route other data we want to go somewhere else.  However, I noticed in this scenario which is not the case.  Also, when I go to the point of the route default somewhere other than the ISP gateway (even to the tunnel Hub ip), I lose all connectivity to the lan Hub.

  Basically, I just need the traffic by talking them through the tunnel on the hub, if all resources and internet access will be charged.  Any advice would be appreciated!

  Hi Ken,

  Not a typical requirement for channel 0/0 to dmvpn hub. To do this, you must:

  1 correct routing on the rays which will point to the tunnel of 0.0.0.0/0

  You can get that by example of routing, static or dynamic:

  IP route (this is to have connectivity tunnel)

  IP route 0.0.0.0 0.0.0.0 (send all traffic through the tunnel)

  I've never tested this scenario - but it would be my test.

• The best way to draw the difference of phase vs. time of two signals

  I have three channels (time, force, displacement) of approximately 1 000 seconds of a sinusoidal test load test data (sampling rate was 100 Hz).  I would draw the difference in phase between the force and displacement (perhaps using a second window 30) according to time.  I tried using a few different analysis functions, but I get what looks like random noise (phase difference between force and displacement is very small and the difference in amplitude is very fantastic - 4 orders of magnitude).  Any suggestion would be appreciated! -Jim

  Hi Jim,.

  The phase channel resulting, that you get with the function FFT DIAdem is in the frequency domain.  If you select a channel data and time in the FFT dialog box, you will get a frequency channel that results as well as the Phase channel resulting.  If you select only a weather channel of waveform data in the FFT dialog box, you will get a Phase of waveform frequency channel resulting.

• Classes in two files .java talk

  Hello, if you have A class in a separate from your main application class in the main .java file source .java file, you can do something like this:

  File main .java
  Class myapp. {
  ClassA joe = new ClassA();
  Joe.doThis ();
  Public int doThat() {...}

  in the other .java file
  Class ClassA {}
  Int doThat() = result;
  Public void doThis() {...}

  What is needed is to see why the call to do can not see the method and has a compilation error, and regarding the call to doThat(), it will not work as is, but how to make the call...

  TKS for your time, J.

  Not sure, I understand that, but here are a few thoughts.

  I'm going to take all these classes are in the same package, or you have used imports for the relevant classes.  I will also assume that the capitalization is not scheduled.

  If the main java class you can do a

  ClassA joe = new ClassA();

  then it should be able to make a

  Joe. DoThis()

  I don't see how you can manage one without the other.

  Now to give placed the possibility of returning to the class in the main routine, you pass a reference to an instance of the class.  Thus, for example, instead of

  ClassA joe = new ClassA();

  use

  ClassA joe = new ClassA (this);

  and change appropriately the manufacturer of finished and you should be able to call the method will be.

  Of course, there is also the static option, but I guess that the treatment you want to do is specific instance.

  I hope this helps.

• Double-Cloud DMVPN spoke Router Configuration

  I have a decided to adopt an architecture dual-cloud DMVPN (1 head of network in the main office, 1 head of bed instead of DR) with the option later to go to double / hub in each of my network places.

  I tried to configure each of the clouds to have its own key.

  Cloud Hub 1 1:

  ISAKMP crypto key KEY123 address 0.0.0.0 0.0.0.0 no.-xauth

  1 2 hub cloud:

  ISAKMP crypto key KEY456 address 0.0.0.0 0.0.0.0 no.-xauth

  Of course, the rays I want to connect to the two clouds not would allow me to use the same simple crypto isakmp key command twice.

  Several of my sites will have 2 internet connections.  Given that I source a tunnel each of these Internet connections, I came up with the following solution:

  talk 1:

  door-key crypto X-RING

  address Gig0/1 (internet connection interface 1)

  preshared key address 0.0.0.0 0.0.0.0 touches 0 KEY123

  door-key crypto Y-RING

  address Gig0/2 (internet connection interface 2)

  preshared key address 0.0.0.0 0.0.0.0 touch 0 KEY456

  Crypto isakmp DMVPN_ISAKMP_X profile

  X-RING keychain

  function identity address 0.0.0.0

  address Gig0/1

  Crypto isakmp DMVPN_ISAKMP_Y profile

  Y-RING keychain

  function identity address 0.0.0.0

  address Gig0/2

  OK... to the question... the first site I tried to connect the two clouds DMVPN has only 1 internet connection!

  Without changing both my DMVPN clouds to the same key (almost all of the examples have this) - how can I make sure that tunnels speaks - has spoken-star work?

  Is there anything else I can match? or create on each configs speaks and hub?

  I tried:

  - identity group match, but couldn't figure out how to set a group name on each of the rays - or the hub also.  Also, no.-xauth wouldn't prevent it being considered?

  -matching fqdn does not seem to work either.

  -vrf is not an option - not applicable
  -telesignalisations behind the ip address do not appear to be an option and seems to complicate the issue too.

  Thank you very much in advance!

  There is something special with ICP when seen DMVPN. PKI or preshared keys is just how isakmp authenticates the session, and there is no difference between DMVPN or Site to Site.

  Basically, you'd have to do these things:

  -create a CA. The basic can be created on some of your routers.

  -create the Trustpoint on each DMVPN hub and spokes.

  -change the type of authentication in isakmp profile of pre-shared key to rsa - SIG.

  You can certainly more trustpoint then one, one for each cloud, but I highly doubt that it is necessary for the public key infrastructure.

  Maybe this doc will be of little help, even if it has too much info:

  http://www.Cisco.com/en/us/docs/solutions/enterprise/security/DCertPKI.html

  If you need, I can bring up some full example site to site with PKI auth.

• DMVPN Phase II flow by HUB

  Hello!
  I have a questions about the phase II of DMVPN.
  -Why the first packets between the spokes will be flow through hub? How can I influence the quantity of this package, or at the time of this kind of flow direction?
  -It is mandatory to use no next hop eigrp is itself and no ip split horizon on Hub only, or the rays also?

  Thank you!

  It is not a three minutes, but up to three minutes if no IPSec tunnel don't talk-to-spoke cannot be established. Once the resolution PNDH finished, which is usually after only a few packets, the traffic is routed normally, and not by the hub. If the tunnel can be established for a reason, everything continues to go through the hub. All this is done for if ensure that there is no loss of connectivity in the initial installation or because of access problems speaking.

  In regards to the cache does not not not in the Center, my guess would be that this is done to ensure that connectivity is always to the rays before providing information that make authorities to the other nodes in the network, but it's speculation.

• Meter with two adjustable phase shift

  Hello

  In this experimental device, I have a print head a TTL pulse-controlled piezoelectric ink jet delivering uniform droplets on a surface. I use the "time" version of the counter output vi (high-/ low-time) because it allows me to very easily change the characteristics of the droplets. I use a strobe approach for imaging the droplets as they are ejected. Basically, a strobe LED light is pulsed at a frequency that exactly matches that of the inkjet printhead. A CCD camera is used in order to imager droplets, who seem "frozen" on the screen due to the stroboscopic effect. Strobe LED is triggered by a train of pulses TTL (two pulse trains come from exits of meter on my USB-6353 X Series DAQ board).

  Of course, I could trigger both the inkjet Printhead and the strobe light with the same output of counter, which would ensure that their frequencies match. But it's really nice to have a 'strobe delay' that allows adjustment of the phase shift between the strobe triggers and printhead. The hardware supplied with the print head has this feature of strobe delay as an external button. It is useful, because you can basically lead through time by turning the button and view the formation of droplets when it leaves the end of the nozzle.

  I have a vi that may trigger sometimes the printhead and the flash, but I can't understand how to adjust a phase shift between the two, while the program is running. It should be possible, but I can't get it. I would really appreciate help with this. Attached is the draft code and a diagram which may help to explain what I want to do

  Thank you very much

  -Matt

  No - forget the INITIAL DELAY.  It's only for the (first) INITIAL pulse.

  You already want to adjust the time / low-time already, no?

  So having a new control called PHASE SHIFT, from scratch.

  Have a variable called OFFSET PHASE CURRENT, from scratch.

  When the PHASE SHIFT is modified (by the user), understand the difference between where he wants to be and where you are (control - PHASE CURRENT OFFSET) and add a lot of time the low TIMES, but only during a cycle.  Basically you're stretching of a cycle.  Store the new value in the course of PHASE SHIFT variable for next time.

• Cisco series ASR DMVPN Phase 3 Support

• DMVPN Design using ISP by modem redundancy alongside with rays.

  I'm working on a new DMVPN configuration with a 3745 on hub site and a 1941 speak it. I have internet via gsm for the first line speaks it and a DSL for backup on talk.

  I have a tunnel on the spokes and the hub interfaces. Currently my VPN tunnel is coming up fine, however we are planing to do a failover from the ISP next with rays. given that in the tunnel interface, I can define only a "tunnel source interface" which is the cell interface gsm, I don't know how to use my ISP one another for the same tunnel interface because it will always launch gsm traffic.

  that I have to create another interface of tunnel with same hub site, or do I need another hub as backup?

  is their any other way to create the loopback interface and initiate this loopback traffic?

  Does anyone have any suggestions on how I have to design? or someone has an idea what could be the problem?

  Thank you.

  Hello

  There are many designs to implement A high-availability in DMVPN.  Basically, the design decisions are based on infrastructure, budget, and if you are looking to implement HA for devices DMVPN, ISP links or both.

  on your scenario, you seem to be looking to implement redundancy for DMVPN HA ISP on the right talk. This scenario can be achieved by a single pivot double-cloud design, with double-hub it may also be more highly available.

  The elements of design for your scenario:

  -2 interfaces tunnel using two interfaces physical sources talked about it.

  -two interfaces of tunnel in the hub, they can share the same physical interface.

  -Point-key: using of protocols of dynamic routing in the two clouds with different 'links between costs', so that the main connection at lower cost, and the second connection has the higher cost (to use at default)

  I hope this helps you

• DMVPN BGP and EIGRP

  I am in the initial phase of research DMVPN.  We currently have an MPLS network running BGP.  Each site has Internet at home as well as a VPN site-to-site is built on the router and talks to an ASA when the SPLM fails.

  I want to implement DMVPN to do away with the site to site VPN and ASA.  I'm going to run EIGRP on routers to connect DMVPN.  Are there any good whitepapers on BGP as the main path and by EIGRP on the DMVPN as a backup?  Or no focus on a general config?

  Thank you

  It's really the main issue.

  With your configuration DMVPN roads will be internal EIGRP of an advertisement of 90, so your default DC prefer DMVPN on MPLS, which is exactly what you don't want.

  There are several ways around this as summarizing through DMPVN, redistribution connected on the sites of the branch in EIGRP so roads DMVPN are external as well and then changing measures etc.

  The other alternative I have ever done so it's for your information is really Cisco have what is called a solution IWAN where DMVPN is performed everywhere that is, even through the MPLS network.

  That would solve your problem of external routes internal EIGRP but IWAN vs is much more than just that, even if you do not need necessarily to implement the entire solution at a time.

  I just thought that it should be mentioned, and if you want more information on this I can direct you to the design guide.
