Abstract
Systems and methods for performing connectivity checks, such as Seamless Bidirectional Forwarding Detection (S-BFD), are provided. A method, according to one implementation, includes receiving, at a responding node, an entry configured to call for a modification of an identification element (from an old identifier value to a new identifier value) used for identifying the responding node with respect to other nodes of a network. The old and new identifier values are cached in a memory device. Also, the method includes providing a reply packet back to an initiating node in response to receipt of a request packet from the initiating node. The request packet is related to a connectivity check for testing the connectivity between the initiating node and the responding node. In addition, the request packet is able to identify the responding node by either the old identifier value or the new identifier value.
