Route means forwarding of packets from one network to another based on network layer information or the path through an internetwork. let me add to this hoping for some additional info but linux newbie already explain it. routing is on layer 3 (network layer) while bridging is on layer 2 (data-link layer)... routing doesnt deal with access method (eg. ethernet access method, token ring access method, etc) unlike with bridging... as what linux newbie said, it will (store and) forward packets from one network to another based on the network layer information... for example, IP for tcp/ip stack while IPX for ipx/spx stack. bridging on the otherhand, deals with the data-link layer... common usage of bridging is to bridge two different access method or data-link layer... like for example bridging ethernet network with token ring network... but of course you can still use bridging to bridge two the same access method but it is not advisable. let me tell you a story that there was two camps between the bridging zealots group vs the routing zealots group that they are debating who will rule to inter-connect networks.... well of course bridging is fast because it will eliminate layer 3 for direct communication but the routing group wins due to the reasons of broadcast traffic and scalability. :-> imagine if the network of networks or the internet are using bridges instead of routers.. one node generate a broadcast traffic, the whole world will receive it. :-> fooler. _ Philippine Linux Users Group.
