AB> Is routing necessary in an IntraNet? If you have more than one network then yes. For one LAN there is no reason. You also want routing when connecting Ethernets with differnet MTU - so hosts in network with MTU of 9000 can talk with this MTU and the router fragments the packets and forwards to hosts in a network with MTU 1500. Etc. It's usually simpler to set up routing than to do the same with VLAN's, bridging etc. But routing usually adds some communication latency. Most (but not all) sensible firewalls are also implemented as routers, so from practical viewpoint you can deploy a router-like firewall more easily. AB> Switch when you can and Route when you must? Well, you can sell more switches with this :) -- Meelis Roos - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
