How important is it to have a routed connection between 2 switches in a routed server farm access layer?
So, what we have are 2 server farm switches in an HA configuration with L3 uplinks from each to a routed distribution layer, as well as L2 trunks between access switches.
How important is it to have a routed connection between the 2 routed access layer switches?
My answer is that it is important. The logic is that the 2 switches are in an HA setup, and that makes it all the more imperative that the IP routing and forwarding information in each switch be the same -- identical/synchronized/converged. This will speed up network convergence in the event of a failure of one of the access switches.
There are others who say that for an ACCESS layer, it is not so important because -- and this is where I get fuzzy regarding the stance -- that L2 switching is faster than routing and therefore....I dont know the rest of the argument. maybe you can fill me in. :-)
