LDP Base Graceful Handling of Resources
After the user has taken action to free resources up, he/she will require manually unshut the
interface or the targeted peer to bring it back into operation. This then re-establishes the Hello
adjacency and resumes the resolution of FECs over the interface or to the targeted peer.
Detailed guidelines for using the feature and for troubleshooting a system which activated this
feature are provided in the following sections.
This new behavior will become the new default behavior in Release 11.0.R4 and will interoperate
with SROS based LDP implementation and any other third party LDP implementation.
The following are the data path resources which can trigger this mechanism:
- NHLFE, ILM, Label-to-NHLFE (LTN), Tunnel Index, P2MP Index.
The following are the CPM resources which can trigger this mechanism:
- Label allocation.
