Hi all,
I'm running MIPL 2.0.2 under Ubuntu Dapper with the 2.6.16 patch. My
testbed setup is almost the same as
http://gnist.org/~lars/doc/Mobile-IPv6-HOWTO/Mobile-IPv6-HOWTO.html. I'm
following the HOWTO and everything works great until the "Movement
detection" part, where I move to the foreign wireless network and the
MN autoconfigures a new ipv6 address and default route from the AR's
router advertisement. The MN should then send a BU to the HA, but it
just never happens.
The network is correctly configured, the routes are working and every
node can ping every other node. Some info about the network:
- Home network prefix: FEC2::/64 (Radv advertises the FEC2::2/64 prefix
with HA flag on)
- HA Address: FEC2::2
- HoA: FEC2::4
- Foreign network prefix: FEC1::/64 (Radv advertises the FEC1::/64
prefix)
- Mobile IPv6 configuration file for the Mobile Node:
---------------------------------------------------------
NodeConfig MN;
DebugLevel 10;
MnDiscardHaParamProb enabled;
Interface "eth1";
MnHomeLink "eth1" {
HomeAgentAddress fec2::2;
HomeAddress fec2::4/64;
}
UseMnHaIPsec disabled;
---------------------------------------------------------
- Mobile IPv6 configuration file for the HA:
---------------------------------------------------------
NodeConfig HA;
DebugLevel 10;
Interface "wlan0";
UseMnHaIPsec disabled;
---------------------------------------------------------
As you can see in the following log, the MN knows it's home, but after I
move the MN to the foreign wireless network there's no BU, even if a new
ipv6 for the foreign network is successfully auto-configured. First,
let's see the mipl HA log:
---------------------------------------------------------

Now let's see the output of "ifconfig eth1" before starting MIPL on the
MN:

---------------------------------------------------------
Now we start MIPL on the MN:
---------------------------------------------------------

---------------------------------------------------------
Let's see ifconfig right after this point in the MIPL MN log. The HoA
(fec2::4 has been assigned to the wireless eth1 interface):
----------------------------------------------------------
eth1 Link encap:Ethernet HWaddr 00:13:02:11:41:4C

----------------------------------------------------------
Now I move to the foreign network:
sudo iwconfig eth1 essid mipl-foreign mode ad-hoc enc off
And the MN mipl log shows this:
---------------------------------------------------------
md_expire_router: expiring router fe80:0:0:0:213:f7ff:fe2a:339 on iface

__md_discover_router: discover link on iface eth1 (5)
md_change_default_router: add new router fe80:0:0:0:213:f7ff:fe23:fbe3
on interface eth1 (5)
---------------------------------------------------------
ifconfig now shows:
---------------------------------------------------------
eth1 Link encap:Ethernet HWaddr 00:13:02:11:41:4C
inet6 addr: fec2::4/64 Scope:Site

------------------------------------------------------------
So a new IPv6 (fec1::213:2ff:fe11:414c) for the foreign network was
successfully configured, but no BU update was sent, and ifconfig shows
that MIPL didn't add the HoA to the tunnel. Now, if I try to ping the HA
or any other node I get:
[EMAIL PROTECTED]:~$ ping6 fec2::2
connect: Invalid argument
Pinging the HA only works if I force ping to use the newly assigned CoA
as source:
[EMAIL PROTECTED]:~$ ping6 -I fec1::213:2ff:fe11:414c fec2::2
PING fec2::2(fec2::2) from fec1::213:2ff:fe11:414c : 56 data bytes
64 bytes from fec2::2: icmp_seq=1 ttl=62 time=1009 ms
What's wrong here???
Thanks a lot for your help!
Regards,
Pedro
