JN0-363 Exam Dumps : Service Provider Routing and Switching, Specialist (JNCIS-SP)

To ensure that MPLS traffic-engineered routes are used without affecting IGP routes in the route tables, the mpls-forwarding traffic engineering setting should be used. This setting allows MPLS to influence forwarding without changing the IGP route selection.References:

Generated routes are a type of route that can be created to summarize and generate more specific routes within the routing table. Unlike aggregate routes, which summarize existing routes and inherit a next-hop, generated routes do not necessarily have to match an existing route and will have a next-hop of reject by default unless specified otherwise.

Nonstop routing (NSR) requires both Graceful Routing Engine Switchover (GRES) and commit synchronization to be configured to maintain routing protocol and forwarding state during a Routing Engine switchover. NSR allows the secondary Routing Engine to take over the control plane without the protocols needing to restart, and GRES ensuresthat the forwarding plane continues operating with the current forwarding table. Commit synchronization ensures that configuration changes are synchronized between the primary and backup Routing Engines.
