Abstract:
Various systems and methods for using strict path forwarding. For example, one method involves receiving an advertisement at a node. The advertisement includes a segment identifier (SID). In response to receiving the advertisement, the node determines whether the SID is a strict SID or not. If the SID is a strict SID, the node generates information, such as forwarding information that indicates how to forward packets along a strict shortest path corresponding to the strict SID.
