RE: Protecting SR policy midpoints (draft-bashandy-rtgwg-segment-routing-ti-lfa)

2017-11-28 Thread Sikhivahan Gundu
Drafts allow a B-Flag to be attached to the Adj-SID, which says that the adjacency is “eligible for protection”. Such an adjacency may perhaps also be interpreted as ineligible for SR policies that are particular that only the selected adjacency must be used to reach the protected node. This preven

Hi, The draft mandates using "post-convergence path" as the backup path. It states one advantage, among others, of doing so as follows: "This .. helps to reduce the amount of path changes and hence service transients: one transition (pre-convergence to post-convergence) instead of two (pre
