Part III continue the discussion wo show when will TI-LFA use a adjacency SID to drop traffic intot the neighbor's Q space.

This video explains TI-LFA Topology Independent LFA (Loop Free Alternate) P and Q space/node, and the notion of PQ node. How P or Q space is calculated, where to find the overlapping PQ node. How IGP metric is affecting the selection of the P Q nodes etc. Note this is not a general video about TI-LFA but more focusing on understanding the PQ space and post convergence path, how these 2 interact with each other.
