It depends on what's going on in your topology. The default
port modes of the Catalyst are dynamic, which means they will attempt to
trunk via DTP. Since the routers don't support DTP this isn't an issue
normally. One of the issues you can run into is that if you configure
transparent bridging on the routers' interfaces and start running STP
the switches will interpret this as an attempt to trunk. The result is
that the switch will think the link is a trunk while the router does not
and you will lose connectivity. To avoid this simply configure the link
as a static access port on the switch.
