Abstract
An apparatus and method for enabling interoperability of segment routing (SR) enabled nodes and LDP enabled nodes in a network domain. In one embodiment, the method may include mapping a first node identifier (ID) to a first segment ID in memory, wherein the first node ID uniquely identifies a first node within a network domain, and wherein the first node is not SR enabled. A message is generated and subsequently transmitted directly or indirectly to another node within the network domain, wherein the message comprises the first node ID mapped to the first segment ID, and wherein the other node is SR enabled.
Claims20
A method comprising:
- mapping a first node identifier (ID) to a first segment ID in memory, wherein the first node ID uniquely identifies a first node within a network domain, and wherein the first node is not segment routing (SR) enabled;
- generating and transmitting a message directly or indirectly to another node within the network domain, wherein the message comprises the first node ID mapped to the first segment ID, wherein the other node is SR enabled.
A non-transitory computer readable medium (CRM) comprising executable instructions, wherein a node in a network domain implements a method in response to executing the instructions, the method comprising;
- receiving a message that comprises first and second node IDs mapped to first and second segment IDs, respectively, wherein the first and second node IDs uniquely identify first and second nodes, respectively, within an autonomous network domain, and wherein the first and second nodes are not SR enabled;
- mapping the first and second segment IDs to first and second interface identifiers, respectively, of the node, wherein the node is SR enabled.
An apparatus comprising:
- a means for mapping a first node identifier (ID) to a first segment ID, wherein the first node ID uniquely identifies a first node within a network domain, and wherein the first node is not segment routing (SR) enabled;
- a means for generating and transmitting a message directly or indirectly to another node within the network domain, wherein the message comprises the first node ID mapped to the first segment ID, wherein the other node is SR enabled.
