Abstract
Methods, systems, and computer-readable mediums for managing forwarding equivalence class (FEC) hierarchies, including obtaining a forwarding equivalence class (FEC) hierarchy; making a first determination that a first hardware component supports a maximum levels of indirection (MLI) quantity; making a second determination that the FEC hierarchy has a hierarchy height; based on the first determination and the second determination, performing a comparison between the MLI quantity and the hierarchy height to obtain a comparison result; and based on the comparison result, performing a FEC hierarchy action set.
Claims20
A method, comprising:
- obtaining a forwarding equivalence class (FEC) hierarchy;
- making a first determination that a first hardware component supports a maximum levels of indirection (MLI) quantity;
- making a second determination that the FEC hierarchy has a hierarchy height;
- based on the first determination and the second determination, performing a comparison between the MLI quantity and the hierarchy height to obtain a comparison result;
- and
- based on the comparison result, performing a FEC hierarchy action set.
A non-transitory computer readable medium comprising instructions that, when executed by a processor, perform a method, the method comprising:
- obtaining a forwarding equivalence class (FEC) hierarchy;
- making a first determination that a first hardware component supports a maximum levels of indirection (MLI) quantity;
- making a second determination that the FEC hierarchy has a hierarchy height;
- based on the first determination and the second determination, performing a comparison between the MLI quantity and the hierarchy height to obtain a comparison result;
- and
- based on the comparison result, performing a FEC hierarchy action set.
