GroupVPN failover to backup router

Group VPN is a trusted group to eliminate point-to-point tunnels and their associated overlay routing. All group members share a common security association (SA), known as a group SA (GSA). The GSA enables group members to decrypt traffic that was encrypted by any other group member. Junos OS confirms the Group VPN redundancy with service redundancy daemon running on routers. Routers with redundancy between them act as Group VPN members.
