ARP Proxy

ARP Proxy

[Moritz Gartenmeister]

hi

i'm not sure, if am right here, so if i am wrong, pleas point me to a source ;-)

how can i reduce arp-broadcasts without routing?

i have physically 2 subnets (500 and 300 clients), logically this is one subnet. my premature/naive 
idea is, to install a linux-bridge and put arp-proxy on it. as long as the proxy has the correct 
entry, broadcasts are not propagated. this will reduce arp-broadcasts.

i know, i have to bend alot of principles, but will it work?

cheers

why bridge when it can be .. router? or you can use a central switch
that can do vlans (with so many client there should be enough funds
for a 2950 catalyst :) .

You shouldn't do this.

A better way would bet to split the subnet into 2 subnets and use a router.

Why would you want to keep all those clients in 1 subnet? If it's because of
netbios, use wins/dns? That's gonna lower your broadcasting quite a bit on
its own.
