QuestionQ59

High Availability

You need to ensure that traffic and routing information remain uninterrupted if the primary Routing Engine fails or switches over to the backup Routing Engine.

In this scenario, which high-availability feature provides this behavior?

  • A nonstop active routing (NSR)
  • B graceful Routing Engine switchover (GRES)
  • C link aggregation control protocol (LACP)
  • D bidirectional forwarding detection (BFD)
Explanation

Nonstop active routing (NSR) synchronizes routing-protocol state to the backup Routing Engine while also using the switchover infrastructure that preserves forwarding state. Consequently, traffic forwarding and routing information continue through a primary-to-backup Routing Engine switchover; GRES alone does not preserve routing-protocol state.
