Abstract
Various systems and methods for integrating ring-protocol-compatible devices into network configurations that also include non-ring-protocol-compatible devices are disclosed. One such method, which can be performed by a network node that supports a ring protocol, involves generating a ring protocol packet and sending that ring protocol packet to a neighboring node. The ring protocol packet includes information, and the presence of this information within the packet causes a network device that receives the ring protocol packet to drop the ring protocol packet unless the network device supports a ring protocol. The information can include a reserved address (e.g., in the destination address field of the packet) as well as a ring protocol identifier.
