Re: [LISPmob-users] setting up a local PxTR

Hi Musab,

Sorry for the delay, it has been one day off in Spain.

Hi Albert,

I am a bit confused here. When you say
"xTR:

  * Set IP of PiTR and PeTR
" Do you meant that I should have both the lispmob-pxtr and lispmob-experimental packages compiled on the pxtr node? Because, on the lispmob-pxtr package there is no option to set it as xTR, that option only exists on lispmob-experimental.
No, this information was there just as documentation for other users. xTR can be official release or experimental, but the official release is more tested and has more xTR functionalities. For PxTR you should use the PxTR branch version and the MS/MR should be the experimental release. It's a bit crazy but in a few month it will be altogether. This point was ok in your configuration file. It means that in the xTR configuration file you should specify this new PxTR to be used. 

Secondly, your point:
"PxTR

  * Set "pxtr-mode = on"
  * *The database-mapping structure of the configuration file is
    reused to indicate the prefixes that will be lisp encapsulated by
    the PiTR*
" If I put the EID prefix of the mobile node here, is it okay to comment out the remaining parameters, such as interface, priority_v4 etc or I have to provide an interface (now which interface?)?
This information should be includes. They are used to specify the interfaces that will be used by the PiTR to send the packets.
If it doesn't work, send me again logs, configuration, and routing information. 

Regards

Albert L.
And lastly, the MS and PxTR are hosted on different nodes, is the configuration of my MS correctly done? 

Thank you.

Hi Musab

To configure the PxTR you should use the following instructions:

xTR:

  * Set IP of PiTR and PeTR

PxTR

  * Set "pxtr-mode = on"
  * *The database-mapping structure of the configuration file is
    reused to indicate the prefixes that will be lisp encapsulated by
    the PiTR*
You also have to configure the routing of your testbed in order that packets whose destinations are EIDs are sent to the PiTR. 
Let me know if this solve your problem

Regards

Albert

Hi Albert,
I have configured lisp MN, MS and PxTR. The communication between the MN and the MS seems to be working well as I can see the 'map register' and 'map notify' messages being sent and received. But once I attempt to ping a correspondent node, I get no response from the PxTR. I have provided my configurations for all the 3 nodes and the logs below. Can you please follow the links to see if you can determine what the problem is?

Hi Musab,
Just one clarification. When LISPmob works as a MS/MR, the MR will only reply to the mappings configured in the MS. It doesn't interact with ddt nodes. 

Best regards

Albert

Hi Musab,
Sure it is! You can checkout the branch 'experimental' [1] which includes support for MS/MR. Make sure to enable Map Server operation in lispd.conf and to fill out all the required parameters there. Likewise the 'pxtr' branch, experimental is not released yet and may contain bugs. 

Best,
Alberto

    Hi Alberto,

    Thanks for your reply. Is it also possible to setup a map-server
    locally? I want to have a full lisp mobile node network in the
    lab please.

    Thank  you.

    Hi Musab,

    In order to use LISPmob as a PxTR you should checkout the branch
    'pxtr' [1] and follow lispd.conf.example instructions to
    configure it. Note well that PxTR code has not been officially
    released and has gone thought little testing. We offer it as a
    best effort, but we can provide little support. The PxTR feature
    will be eventually merged into the upcoming 5.0 release.

    Best,
    Alberto

        Hi,

        I recently learned that I can set up a PxTR in the lab with
        the new lispmob-experimental (potentially lispmob 0.5.0). I
        have downloaded the package but can't set up the tunnel
        router and other relevant components as there is no
        documentation yet. Can someone please guide me towards
        setting up LISP locally in the lab?

        Thank you,
