MSR series has inherited the reliability of R/AR series that is guaranteed by hardware and software two aspects.?
MSR series uses VRRP redundant backup to enable hot backup among two or more MSR devices, and guarantee the interoperation of devices from different vendors as the VRRP protocol is a public standard. By leveraging a flexible and perfect backup center mechanism, MSR series provides outstanding backup function for communication lines. By specifying a primary interface and corresponding backup interfaces, and adjusting the parameters of backup interfaces like backup preference and switch time, the backup interfaces can take on its work when the primary interface failed without affecting carried services, and thus improving the reliability of communication lines. MSR series uses dynamic standby of routing from H3C. As a new backup mode, it uses traditional DCC (only supporting polling DCC) function to dynamically maintain dial-in lines, i.e. routing-based dial-in backup. With the aggregation time and relevant features of dynamic routing protocols, this function integrates backup and routin
