TI-LFA and Remote LFA Node Protection Feature Interaction and Limitations

LFA Protection Option Applicability describes the order of activation of the various LFA types on a per prefix basis: TI-LFA, followed by base LFA, followed by remote LFA.

Node protection is enabled for TI-LFA and remote LFA separately. The base LFA prefers node protection over link protection.

The order of activation of the LFA types supersedes the protection type (node versus link). Consequently, it is possible that a prefix can be programmed with a link-protect backup next-hop by the more preferred LFA type. For example, a prefix is programmed with the only link-protect backup next-hop found by the base LFA while there exists a node-protect remote LFA next-hop.
