I have a question about traffic traversing a layer 3 switch (6509). Currently, we have a 6509 acting as the gateway for all nodes. There is consideration of moving the gateway to the internal routers. If the gateway routers would have router-on-a-stick, and an end-node try to communicate to another node on a seperate vlan (but on the same switch); would the traffic ever leave the backplane of the switch? Baring the nodes default gateway are now changed to the gateway routers.
*** If anyone could add the pros and cons of switching the gateways, that would be excellent. ***
Solved! Go to Solution.
I'm curious as to what the benefit of this proposal is. Router on a stick over svi on an l3 routing switch? Must be one hell of a router.
