Abstract:
1. A method comprising: provisioning a first virtual connection between a first device and a second device; provisioning a second virtual connection between the first device and a third device, wherein the third device is different than the second device; configuring a first bridge function on the first device to control switching associated with the first virtual connection; configuring a first active subconnection and a first standby between the first bridge function and the second device; configuring a second bridge function on the first device to control switching associated with the second virtual connection; configuring a second active subconnection and a second standby between the second bridge function and the third device; configuring a parent bridge function on the first device to control switching between the first bridge function and the second bridge function, wherein the first virtual connection comprises an active connection and the second virtual connection comprises a standby connection; determining that both the first active subconnection and the first standby subconnection have failed; sending a notification message to the parent bridge function when both the first active subconnection and the first standby subconnection have failed; and switching traffic, by the parent bridge function, from the first virtual connection to the second virtual connection in response to the notification message.
