I"m having some difficulty setting up routing tables using Freebsd to route
to a sparc2. I have PPP going on the bsd box. It continues to try and route
the path to the provider thru the ethernet to the Sun.

I am wondering what this bpf does? I see it on boot up. Here is dmesg:

....
relevant parts

ed0 not found at 0x280
ed1 at 0x300-0x31f irq 11 maddr 0xd8000 msize 16384 on isa
ed1: address 00:00:c0:75:35:92, type SMC8216/SMC8216C (16 bit) 
bpf: ed1 attached

.....

changing root device to wd1a
bpf: lo0 attached
bpf: ppp0 attached
bpf: ppp1 attached
bpf: sl0 attached
bpf: sl1 attached

I have two modems attached which I presume is why I have ppp0 and ppp1 as
well as sl0 and sl1.  This is actually becoming more difficult than it ought
to be.

The Question of the day is:

What is bpf, and why is both the ethernet and the ppp interface attached to
it? Is this part of the problem?

Also, why is the route to my internet provider getting routed thru the
ethernet.  If I leave the ethernet down on boot up I can connect with PPP
fine.
