Abstract

A method implemented by a controller configured to implement a Border Gateway Protocol (BGP). The method includes transmitting a first Update message to a node, the first Update message comprising binding information for a segment routing (SR) path going through the node or receiving a second Update message from the node, the second Update message comprising the binding information for the SR path going through the node, the binding information including a binding segment identifier (SID) and a list of SIDs; transmitting a third Update message comprising binding protection information corresponding to the binding information to a protecting node, the binding protection information including the binding SID, the list of SIDs, and an identifier of the node; and instructing the protecting node to use the binding protection information to prevent a failure in communication if the node fails.
