Abstract
Methods and systems for providing redundant network connectivity across a network using a tunneling protocol by dynamically moving a TLS tunnel between master and slave switches based on relative connectivity provided by the switches are disclosed. A standby routing protocol executes on the master and slave switches to monitor the relative connectivity. In response to detecting that the relative connectivity of the slave switch exceeds that of the master switch, the standby routing protocol reverses the roles of the master and slave switches, thus moving the TLS tunnel to the new master switch.
