Only if you plan on having bridged links in parallel with routed links. You need to be very careful about running bridges providing links in parallel to a router. Bridges may forward broadcast requests which will confuse the router there are lots of protocols you may not think of filtering (e.g. ARP, Apple ARP over 802.3 etc. etc.). Also, DECnet routers have the same MAC address on all ports. This will probably cause the bridge to think it is seeing an Ethernet loop.
