Abstract
Various systems and methods for bypassing one or more non-capable nodes. For example, one method involves a capable node determining that an adjacent node is non-capable, where capable nodes are configured to implement a data plane capability and non-capable nodes are not. The method then involves identifying a downstream node that is capable. The downstream node is on a shortest path. The method also involves generating information that identifies a tunnel to the downstream node.
Claims1
A method comprising:
- detecting a plurality of equal cost nodes;
- determining whether one or more nodes of the plurality of equal cost nodes are capable, wherein
- a capable node of the one or more nodes is capable by virtue of being configured to implement a data plane capability, and
- a non-capable node of the one or more nodes is non-capable by virtue of not being configured to implement the data plane capability;
- in response to at least one of the plurality of equal cost nodes being capable, selecting a capable one of the at least one of the plurality of equal cost nodes as a next-hop destination for network traffic;
- and
- in response to none of the plurality of equal cost nodes being capable,
- selecting a non-capable one of the plurality of equal cost nodes as the next-hop destination, and
- implementing a path from a source node to a capable downstream node,
- wherein
- the source node implements the data plane capability.
