Message-ID: <20030320150619.X6897@subzero.kw.ua> MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hello FreeBSD gurus, suppose we have FreeBSD box `A' with 3 network interfaces (ip unnumbered or numbered - shouldn't matter). This 3 interfaces form 3 parallel IP channels to some single destination `C' (let's think of another FreeBSD box `B' with another 3 interfaces at the other end and `C' being an alias to lo0 of `B' box). Than let's consider either 3 equal static routes to `C' set at `A', or OSPF with 3 equal cost routes to `C' from `A'. Is it possible to tell kernel to route packets between `A' and `B' in a round-robin way, so that each of 3 channels handle 1/3 of a total consumed bandwidth? Something like "equal-cost multipath" feature of Cisco IOS?
