Subject: [PATCH 2 of 5] IPv6: only update the lifetime of the relevant temporary address
Date: Sun, 23 Mar 2008 21:46:10 +0100 [thread overview]
Message-ID: <5e50b19fbb757f080905.1206305170@pirzuine> (raw)
In-Reply-To: <patchbomb.1206305168@pirzuine>
IPv6: only update the lifetime of the relevant temporary address
When receiving a prefix information from a routeur, only update the lifetimes
of the temporary address associated with that prefix.
Otherwise if one deprecated prefix is advertized, all your temporary addresses
will become deprecated.
