I mean that:
1. If you use HISADDR, ppp(8) will automatically re-add route after link
is brought down and then back up.
2. If you use static IP address in ppp.conf, ppp(8) will add that route
only once. This route will also cache local interface address at the
time the route is added. Execute `route -vn get default' to see what
I am talking about.
3. The routing code was fixed to delete routes which use non-existent
interface addresses. This code will wipe such a route.
4. If you need routes with static gateway addresses, put `add!' command
to ppp.linkup script. This way, routes will be activated every time
the link is up, and will use the correct source IP address.
5. This affects not only ppp(8). Add default route that points to the
LAN; change the IP address on interface; observe that the default
route has gone away. The reason is that if we don't do this, we
may end up using the old (now non-existing) local IP address.
