Re: [mpls-linux-general] Diffserv & Van den Berghe Patch

[Steven V. d. B. <ste...@in...>]

Hi Filip (and all MPLSers),

First of all, my excuses for the late response and the follow-up on the
mpls patches. It's been quite busy lately, and although the patches are
almost stable now, i haven't put them through the final test phase. This
will be done asap. These will hopefully resolve all the remaining problems
(i'll release 3 patches: the DS patch, multiple table support and
statistics support).

Concerning your problem:
  - i think both labels/exp combinations get registered but don't get
printed (this is just from the top of my hat).
  - if this isn't so, i'm very sorry but the patch used was indeed a
dreadful thing with lots of bugs in it. I'll check if it works with the new
patches and release them asap.

To be certain, could you check with:

mplsadm -v -A -B -O gen:120/1:eth0:ipv4:10.1.1.2 -f <some fec>
mplsadm -v -A -B -O gen:120/2:eth0:ipv4:10.1.1.2 -f <another fec>

that there is indeed no possibility to set multiple EXPs (PS use ethereal
to check which EXP the packets are getting)

Thanks,
Steven
