The exhibit highlights in blue the primary path of a segment going from router S to router D. The exhibit also shows a backup path. The protected link fails and fast re-route is triggered on router S. If the backup path has been calculated using standard LFA, how many SIDs are included in the label stack of the data packet forwarded to router R1?
For any of the LFA methods to work properly, there must be a router in the backup path that will forward traffic addressed to the destination without sending it back to the source. Which of the following statements describes the way R-LFA selects such a router?
Based upon the exhibit, which of the following statements regarding the configuration is FALSE?
Based on the exhibit, which of the following is a viable option for the Path Computation Element (PCE) to obtain all the necessary topology and traffic-engineering information from the network, so that it can calculate LSP paths on behalf of the PE routers?
Which of the following statements about primary and secondary SR-TE LSP paths is FALSE?
Based on the exhibit, which of the following statements about fast re-route for flex-algo instance 129 is TRUE?
