Will it work OK in theory, or > should I spend the $8K on a 3640 ? As long as you're just doing Ethernet, you might want to consider the 2948G-L3 as an alternative to a 3640. IP routing in hardware, 48 10/100 ports and 2 Gigabit ports. *Way* more backplane bandwidth and pps than the 3640. Con: No access lists on the 10/100 ports. We're using these as pure routers (no bridging), and they're working very well. (We used to have the 2948G-L3 do bridging also, that did *not* work very well.)
