Situation with remote site using frame-relay as main transmission method (768k), also has vpn connection with dsl as backup (640k). Would like to configure to automatically use backup route upon failure. The remote site is using 2611 as primary router (frame-relay to central site) and Nokia/Checkpoint as VPN router. Central site devices involved: 3662 (frame-relay) and Nokia/Checkpoint (VPN) Maybe use GRE tunnel with OSPF as routing protocol? Anyone have experience with this? Any advice would be appreciated.
