![]() Layer 3 IP bandwidth aggregation might not be completely impossible but it would involve some tricky ARP deception and faking link negotiation for any dynamic aggregation. That means $$$ technical (skill x time) and/or $$$ equipment which suggests buying a commercial router with excellent OEM link aggregation as a cheaper path than DD-WRT and home wireless router. Because the only avenue I can see is a device at the other end that is smart enough to convince dumb ASIC in home wireless router that reverse path on second port is not viable (too costly, etc) alternative path so loop does not form. Layer 2 switch to switch bandwidth aggregation is either impossible with basic ASIC due to network loops or not cost effective. On ordinary dumb layer 2 switch as in the cheapest wireless routers.įailover link aggregation (no bandwidth gain just spare links) should be something possible by manipulating STP and port disable at worst. The basic equation for switch networks is NxN where N= number of ports. In general reduction in total ports and in number of supported aggregated ports will greatly reduce the number of gates. (Nope not tearing its welded metal case to find the chip number.) That chip is probably cheap now. So if originally the router isn't equipped with this function can't be activated via FW DD-WRT or other type of software? Or would you need a specific update that is not currently implemented by DD-WRT?Īre we sure none of the routers have a slightly upgraded switch ASIC? For instance the old Netgear GS108E switch supports a single LACP link - maybe 2 port only. If I understand well, Link aggregation is implemented at the hardware level through ASIC technology. You're probably better off to get a separate managed switch that supports link aggregation, put all your devices on that managed switch and just use the router to do routing. ![]() Seeing as most of the routers have pretty basic switch ASICs in them, you're probably not going to have a whole lot of luck with this. Link aggregation as used for something like a NAS with dual LAN ports is more of a function of the switch ASIC than it is of the routing. ![]()
