Howdy,
Question?
Our internal network, not including WAN, has 4 routers all in bridging mode (no spanning tree), don't ask why we don't subnet and route. All the traffic is IP. The routers are connected via an ethernet cable backbone.
Here's the question. I have an AGS+ with 3 6 port MEC boards. If I were to connect the other 3 routers to the cisco and use it as the backbone, would I see better performance, assuming that now it would be a high speed bus backbone? Would it be better to place the other 3 routers on 1 card and rely on the packet switched rate between ports or spread them across cards and rely on the bus?
As a side question while I have your ear, what are the performance characteristics on the Cisco with respect to bridging vs. routed IP traffic throughput?
FYI, we tried this scenerio using a Wellfleet at the top of the tree and performance sucked between leaf routers.
The objective here is to improve the backbone performance with the existing hardware. FYI, the routers are, 1 Cisco AGS+, 2 Wellfleets, 1 Alantec.
