Abstract:
An apparatus and method are disclosed for fast reroute (FRR) for native segment routing (SR) traffic. In one embodiment, a node receives a packet that includes a segment routing (SR) segment identifier (ID) stack. The node determines what type of segment is designated as the active segment in the segment ID stack. Based, at least in part on the type of active segment, the node selects an update routine out of several possible update routines and performs the selected update routine. The update routine modifies the segment ID stack.
