the CVS versions of the source files are not related to the net-tools
release version. 1.57 was released in May 2000. <http://www.tazenda.demon.co.uk/phil/net-tools/>

the reason why the default route for gateways(!!) was not possible is not a
bug or missing feature, but by intention, to avoid a route on a exterior
gateway which would also route site and link local addresses.

yes because site and link local routes are not matched by 2000/3

2000/3=0010xxxx...
fe80  =11111110....

yes, but if you add 2000::/3 you do not have a default route which routes
site and link local addresses, which is the idea behind using that prefix.
So it is not a good idea to actually use "default" aka 0::/0. (unless 2.4.20
is not routing those prefixes, which I have to check in the code -or- you
manually make sure you habe site/link local point to somewhere else).

trust me :)
