350-501 Networking Practice Question
A service provider is deploying BGP PIC (Prefix Independent Convergence) for edge routers. What is the primary benefit of BGP PIC?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It provides fast convergence by pre-installing backup paths in the FIB
BGP PIC provides fast failover by precomputing backup paths in the forwarding table, enabling sub-second convergence upon failure, independent of the number of prefixes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
It provides fast convergence by pre-installing backup paths in the FIB
Why this is correct
Correct; backup paths are precomputed and installed.
- ✗
It reduces the number of BGP updates during a flap
Why it's wrong here
PIC does not reduce updates; it pre-installs backups.
- ✗
It reduces the memory usage on the router
Why it's wrong here
PIC may increase memory usage due to backup paths.
- ✗
It eliminates the need for BFD
Why it's wrong here
BFD can be used with PIC but is not eliminated.
