1. A responding node comprising:
a processing device, and
a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
receive an entry configured to call for a modification of an identification element used for identifying the responding node with respect to other nodes of a network, wherein the entry calls to modify the identification element from an old identifier value to a new identifier value,
cache the old identifier value and the new identifier value in the memory device, and
provide a reply packet back to an initiating node in response to receipt of a request packet from the initiating node, wherein the request packet is related to a connectivity check for testing the connectivity between the initiating node and the responding node, and wherein the request packet identifies the responding node by either the old identifier value or the new identifier value.
