2.5. Operational State 2.5. ISO parameters
Some ISO parameters may be required.
This module augments interface configuration model to support ISO
configuration parameters.
The clns-mtu can be defined under the interface.
2.6. IP FRR
This YANG model supports LFA and remote LFA as IP FRR techniques.
The "fast-reroute" container may be augmented by other models to
support other IPFRR flavors (MRT ...).
The current version of the model supports activation of LFA and
remote LFA at interface only. The global "lfa" container is present
but kept empty to permit augmentation with vendor specific properties
like policies.
Remote LFA is considered as a child of LFA. Remote LFA cannot be
enabled if LFA is not enabled.
The "candidate-disabled" permit to mark an interface to not be used
as a backup.
2.7. Segment Routing
This item is still under discussion and some part of the proposed
configuration may fit in a segment-routing specific model.
2.8. Operational State

container is divided in multiple components: container is divided in multiple components:
