Abstract
Segment Routing is an emerging technology in Multiprotocol Label Switching (MPLS) network, Seamless Bidirectional Forwarding Detection (BFD) over these networks is used as Operations, Administration, and Maintenance (OAM) mechanisms to provide fast switchovers and thus meet customer Service Level Agreement (SLA). BFD running over Label-switch Paths (LSP’s) can have MPLS/IP encapsulation in forward and backward directions. In case of Seamless BFD (S-BFD) running over Segment Routing-Traffic Engineered (SR-TE) networks, it may happen that BFD switches to a different MPLS/IP path instead of user configured MPLS path thus compromising the guaranteed SLA.
