Just wondered which is the prefered method for connecting two switches so there is a routable connection between each switch.
Would it be by a configuring a layer 3 port on each switch and assigning an ip address to each port.
Using a layer 2 trunk between each switch and create an SVI on each switch in the same network?
If you don't need to span VLAN's between the two switches (or beyond?) then the preferred method is to use routed interfaces (no switchport) and place the IP addresses directly on the physical interfaces. The reason for this is it removes the layer-2 issues of STP - Interfaces don't have to go through Listening, Learning & Forwarding states and immediately go Up when connected. There isn't the possiblily of someone screwing around with VLANs and/or other trunks on the switch and causing an STP reconvergence on the link etc.
If you must use SVI's and a trunk then make sure the bandwidth statements of the routed interfaces are correct as they will default to either 100Mbps or 1Gbps depending on which switch or router you are working on. With physical interfaces the bandwidth will be correct.
Have a read of the Layer-3 access design guide on the SRND site
