I want to know how I can put two statics default routes on a linux machine: one route with a preference inferior at the other in order to switch via the other when the first gateway fall, and if it''s not possible -what I think- I want know how I can implement this with gateD. --------------------------------- Yahoo!

Stef,
Thanks for the reply.
I want my bridge to "emulate" a rate limit on the transmitter of the
device
connected to that particular bridge interface. That''s why I need an
ingress
qdisc on each and every interface of my Linux bridge. This is what I tried:
tc qdisc add dev eth4 handle ffff: ingress
tc filter add dev eth4 parent ffff: protocol ip prio 50 u32 match ip \
src 0.0.0.0/0 police rate 100kbit burst 10k drop flowid :1
I didn''t obeserve any rate reduction though. I suspect that on the
bridge,
packets are being forwarded and therefore the ip-related matches have no
effect. How can I have the ''police rate 100kbit'' portion of
the command
without the ip-related arguments?
Thanks,
Marcelo.

Can you test it without a switch? Connect the box to a hub, send some data and record the speed.
