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

Mon, 04 Mar 2013 01:11:28 -0800 

Dear Albert,
I forgot to mention that i am connected to the internet from my school network. So to get access to the internet, i must pass through the gateway. I tried to use its address as RLOC (address returned by the command : host proxy ), but it still does not work ! 


i used also my phone as a router and its address as RLOC, but i does 
not work either.



How can i get a "publicly routable RLOC" as you said, since i am not 
directly connected to the internet ?


Best regards ,

Anas

Dear Anas,

The current implementation of LISPmob requires that the host has a
publicly routable RLOC, which is neither firewalled, nor behind NAT.

The encapsulated or data packets you are sending are using the 
private

address as RLOC. As a consequence of this, other nodes doesn't know
how to reach your pc.
Regarding the Encapsulated Map Request that you see, they are
probably generated by your operation system or applications you have
installed. Once LISPmob is running, the routing table is modified to
all packets go through the lisptun0 interface. If no map cache entry
is found for this entry, an encapsulated map request is generated. As
you don't receive the map replay due to the private address of the

RLOC, this encapsulated map request are continuously generated as 
long

new packets are received in the lisp tun interface.

Regards

Albert

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

• 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.
