Re: MPLS patches

I can already run ospfd on NetBSD without using MPLS or ldpd.
What advantages does MPLS have over what I can do today?
In NetBSD now ? Probably none. Maybe yes, only if you have an already
MPLS enabled network and want to take some load from your routers (this
is also doubtable). Also maybe if you want to control the exit point of
packets with a certain destination from MPLS domain in case your NetBSD
is edge LSR.
I believe that MPLS may be useful for a pet project, but I do not know
if I could justify adding MPLS to the kernel.
First of all I don't think the overhead is that much. Also there will be
no MPLS code in your kernel unless you want too. I don't plan to enable
it in GENERIC, INSTALL etc. I think the patch has options MPLS in
GENERIC but this will be fixed.

I think it's justified for future developments in this area that I want
to happen in NetBSD. I'm pretty interested to continue the work in this
area.
or just setup them manually.
How do I do that? Can you give some examples?
Currently, ldpd is set to listen on a PF_ROUTE socket for intersting
routes and first of all, advertise to its neighbours about prefixes
added/removed and second of all if it's necessary changes that route to
point to an MPLS neighbour. So, in order to answer your question, adding
normal IPv4 routes should be enough. This is not very smart for the
moment but I hope to integrate ldpd with openbgpd sooner or later and
get rid of this behaviour.
