FreeBSD 4.5 + ISL =)

  1. Hey All,

    I posted here several months ago looking for info on using ISL with Linux.
    I never could find the kernel patch, however I stumbled across a FreeBSD 4.x
    patch today. Skeptical, I blew away an OpenBSD box & installed FreeBSD 4.5
    (the most recent version the patch supports).

    The diffs applied cleany; compiled a kernel with ipf and wowzers... it
    actually works! Cheap router on a stick =) I'm using it with a Realtek
    8139 and so far it's pretty cool with a Cat1924.

    If anyone's interested I can throw together a mini-howto which includes
    basic zebra, ipf and serial console. I realize ISL is way out of vogue and
    there's dot1q support for everything, but it's fun getting this old stuff to
    work.


    Cheers
    mosfet

  3. Sure. It may take a week or so to clean up my notes but I will definitely
    make it available.
