alternatives to private RFC-1918 addresses on public routers
- From: William Allen Simpson

When I complain, I prefer to suggest alternatives. In this case, the
two that come to mind are:
1) unnumbered interfaces. I've used these with PPP for years, but as
I remember, there was a problem with Ciscos. Has this been fixed?
2) host routes. Rather than creating /30 subnets for links (wasting
2 addresses for each 2 used on a link), go all the way and use /32
for each address. This make the local routing table a bit bigger,
but the entries are rarely used, and aggregated at the boundaries.
Isn't there a link around somewhere on this?
What about a link for bogon filters to use at boundaries?
