I have a network consists of 4 sites, kindly see the attached drawing.
The four site connected to each other using SDH network.
But the problem is that from the Catalyst 6500/FWSM side the WAN is appears as a shared single subnet. And for example to reach site C from A. I don't know which path is used.
Is it possible to redesign this network so that I can control the traffic on the ring and perform load balancing.
I am thinking to implement a new catalyst switches between the FWSM and the IP Prisma in each site and configure a trunk link that tags two WAN VLANs; so that for example from Site A will be two logical interfaces one for site B and one for site A.
Is the Prisma support this design? Or is there any other good idea?
