Hi!

The output of netstat is fixed but what about the route command?
I would like to add or delete a route like "ff01::%fxp1/32" manually.
The route command complains: "hostname nor servname provided, or not known"
when I use the "%interface" notation.

Rainer.

> Bredehorn> FreeBSD 8 uses a strange notation for multicast routes with interface local scope something like:
> Bredehorn> ff01:3::/32
> Bredehorn> Here '3' is the scope id of the interface.
> 
> Bredehorn> OpenBSD uses the same notation as proposed in RFC 4007 for link local scompe multicast addresses:
> Bredehorn> ff01::%fxp1:/32
> 
> Bredehorn> Why does FreeBSD use a different notation?
