I have a private fiber network connecting 5 locations together that uses RSTP for redundancy. I want to utilize Cisco PIX VPN over a public Internet connection as backup between to of these locations. Can this VPN link be configured to participate in RSTP? When the fiber goes down I want this backup link to go active.
Has anyone else done this using a VPN through the public Internet? I will be needing about 10mbs throughput on the backup link. Any advice on which PIX model to go with?
