Just been working my way through the PPP code - which doesn't actually appear
to have changed.
However, the netinet/in.c does have some comments in the SVN history about
deleting the loopback address, this appears to have been merged in as part of
the 8 release cycle (r197231 perhaps) (though I'm not an expert at SVN etc)
What should happen when there are multiple interfaces with the same address.
When I have two tunnels configured they show up as (eg)
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1398
options=80000<LINKSTATE>
inet 10.0.5.1 --> 10.0.0.31 netmask 0xffffffff
Opened by PID 12616
tun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1398
options=80000<LINKSTATE>
inet 10.0.5.1 --> 10.0.0.32 netmask 0xffffffff
Opened by PID 12630
If the loop back address is 10.0.5.1 and closing one of them deletes the
loopback what should happen? Should it delete all routes that refer to
10.0.5.1?
