A bridge, in the context of this +standard, is a device that connects two or more network segments and operates +at the data link layer (Layer 2) of the OSI (Open Systems Interconnection) +model. The purpose of a bridge is to filter and forward frames between +different segments based on the destination MAC (Media Access Control) address. -The bridge-utilities are maintained at: - git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/bridge-utils.git +FAQ +=== -Additionally, the iproute2 utilities can be used to configure -bridge devices. +What does a bridge do? +---------------------- -If you still have questions, don't hesitate to post to the mailing list -(more info https://lists.linux-foundation.org/mailman/listinfo/bridge). +A bridge transparently forwards traffic between multiple network interfaces. +In plain English this means that a bridge connects two or more physical +Ethernet networks, to form one larger (logical) Ethernet network. +Is it L3 protocol independent? +------------------------------ + +Yes. The bridge sees all frames, but it *uses* only L2 headers/information. +As such, the bridging functionality is protocol independent, and there should +be no trouble forwarding IPX, NetBEUI, IP, IPv6, etc. + +Contact Info +============ + +The code is currently maintained by Roopa Prabhu <roopa@nvidia.com> and +Nikolay Aleksandrov <razor@blackwall.org>. Bridge bugs and enhancements +are discussed on the linux-netdev mailing list netdev@vger.kernel.org and +bridge@lists.linux-foundation.org. + +The list is open to anyone interested: http://vger.kernel.org/vger-lists.html#netdev + +External Links +============== + +The old Documentation for Linux bridging is on: +https://wiki.linuxfoundation.org/networking/bridge |
