Re: [LISPmob-users] Some problems when using LISPmob

Wed, 06 Mar 2013 03:08:18 -0800 

Hello Lori,

We finally got a public address from our network administrator.
Could you give us a valid EID so we can pursue the implementation of LISPmob ? 

Thank you.

Hello everybody,

I am currently working on LISP and trying to implement it using the
LISPmob solution.
I am actually facing some problems and would be very happy if someone 
could help me resolving them.

My configuration :

• I am using the following EID : 153.16.254.1/32


How did you choose this EID?  Unless you have a private testbed, you
need an EID allocation for participating in the Beta network, and a
Map-Server or several Map-Servers must be provisioned with this
allocation. You can then only Map-register to the Map-Server(s) where your EIDs are provisioned. IFAIK, you have not yet been provisioned an EID.
As Albert has noted in this thread, you need a publicly routable RLOC on the device running LISPmob to connect to the Beta network. When you can confirm with the debug output that Albert mentioned that you can obtain 
a valid RLOC on one of your devices, we will provision you an EID.

Looking forward to hearing from you,
-Lori
• my RLOC : 172.20.10.4 (since i am connected to the internet at home 
and this is the private address assigned by my router OR shall i use
its address ? )
• the mapping system (Map server - Map resolver) :  217.8.98.46
(retrieved from http://www.lisp4.net/images/lisp-ddt.pdf)

The problems noticed :

• I can see a map register with my EID towards the map server when
LISPmob starts.
• Then immediately, there are several Encapsulated Map Request sent to 
those addresses 62.201.129.203 and  62.201.129.201 (  although i am
not sending anything to them at all ! )
Please find below the configuration file lispd.conf and the logs, and attached a wireshark capture of the traffic i am seeing on my wireless 
interface.

Best regards,

Anas ZAKKI
