Should be 512MB for a simple setup (i.e. BGP/IGP, STP). However, as you enable more feature/module that is known to consume lots of memory (plan and monitor before doing so), you need to upgrade to 1GB.
I understand that I need the memory for the routing tables.
However the previous poster warned about high CPU usage on the 4500, but to my understanding the Sup6E is doing hardware based routing so CPU usage should not be an issue.
I know for sure that the Sup720BXL can do all we need but the Sup6E has all the features we require and would be adequate to our needs. I only need to be sure the Sup6A can handle 2 full BGP feeds without any problems when upgraed to 1GB of RAM.
