350-501 Networking Practice Question
A service provider deploys BGP route reflectors in the core. Which mechanism prevents routing loops within the route reflector cluster?
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
✓
Originator-id attribute
The originator-id attribute is set by the route reflector to the router-id of the originating router, preventing loops by checking if the originator-id matches the local router-id.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Next-hop-self command
Why it's wrong here
Next-hop-self does not prevent loops.
- ✓
Originator-id attribute
Why this is correct
Originator-id identifies the originator; if a router receives its own originator-id, it discards the route.
- ✗
Cluster-list attribute and cluster-id
Why it's wrong here
Cluster-list prevents loops between clusters, not within.
- ✗
AS_PATH loop detection
Why it's wrong here
AS_PATH prevents AS loops, not iBGP loops.
