MIPL2 has some interface preference mechanism implemented. You can get more information in the mip6d.conf manpage (see the MnIfPreference item). > If an interface fails on the MN, how does the other interface > provide a means for recovery by redirect traffic through it? from > the debug screen of mip6d it seems to me that HoA of the working > interface is used as a CoA for the failed address? > The MnIfPreference allows to use several interfaces sequentially: the interface with the lowest preference will be preferred. If this interface becomes down, another one with a higher preference will be used. The tunnel is moved from the failed interface to another, thus redirecting the traffic through this new interface. The CoA of this new interface is used as a new CoA (to replace the one that was on the failed interface), thus a new binding update is sent to the HA to update the binding. Note that the HoA is never used as a CoA. If you want to use multiple interfaces at the same time, you may be interested in the Multiple CoA implementation available here: http:// software.nautilus6.org/MCoA/ Regards, -- Romain KUNTZ [EMAIL PROTECTED] Louis Pasteur University - Networks and Protocols Team _______________________________________________ mipl mailing list [email protected] http://www.mobile-ipv6.org/cgi-bin/mailman/listinfo/mipl
