AW: [support] Delete tunnel with MCOA on HA

[Thomas Kempf]

Hello,
 
I traced again and I can see the BU with lifetime == 0 on the remaining tunnel. But the HA doesn't take down the tunnel on its side. I can furthermore see, that the deamon is sending three ack's back on the dead link. 
 
Best regards,
Thomas

Hello,
 
I just tested this and I can't see a BU with lifetime == 0.
 
Do I need to configure something special?
 
Thanks,
Thomas

Hello,
 
I think, normally when the MR a lose a connection (and therefore a CoA), the MR sends a BU (for that CoA) with a lifetime equal to 0 to deregister it on HA side. This BU is sent in the remaining tunnel .
 
Can anyone confirm this ? Or perhaps this behaviour is not the default ?
 
Etienne

Objet : [support] Delete tunnel with MCOA on HA



Hello all, 

I'm using the MCoA and have a question for the optimization of the throughput. The mobile router (MR) has e.g. two tunnels up. It looses one wireless connection and takes down on the mobile router one tunnel. The tunnel still exists on the home agent (HA) as long as the timer expires and the mip6d takes down the tunnel. Can this somehow optimized? Is it possible that the MR deletes the tunnel also on the HA with a message over the existing tunnel?

Or is the only solution to optimize the timers? 

Thanks, 
Thomas
