Anybody who does any sort of home-brew routing NEEDS to read
this post:

Forwarding (routing between multiple interfaces) and
filtering
(ipfw) IIRC with quad Intel e1000 NIC:

Dual Intel Xeon 2.8GHz:		240Kpps  12k L1 cache
Single Intel Xeon 2.8GHz:	380Kpps	 12k L1 cache
Core 2 Duo 1.8Ghz:		420kpps	 12k L1 cache
Single Pentium-M 1.8GHz:	550Kpps	 32k L1 cache
Dual AMD opteron 2GHz:		890Kpps	 64k L1 cache
Single AMD opteron 2GHz:	970Kpps	 64k L1 cache

All these hosts had 255 vlan interfaces with about 3000
routes and
about 30000 firewall rules, with a good spread of packets
between
the interfaces with polling and fastforwarding.  I struggled
to
generate enough packets to load the AMD routers.

Quite interesting data, no? Especially when you can now get
3GHz opterons 
with 128k of L1 cache? 

How sweet is a sub-$1k router that can do multiple gig-e's
at 1.5mpps? 
Sounds like a dynamite platform for high-end datacenter CPEs
that are soft 
on dynamic routing...and even the open-source dynamic
routing is 
reasonably solid these days...

I can't believe I am about to ask this on a public mailing
list, but..

Has anyone tested this in even a remotely production
environment, while
running any sort of MPLS LDP as a LSR?
