Question 15/107
Which of the following statements is false about the default processing of the next hop address when a BGP device advertises a route?
Correct Answer: B
Comprehensive and Detailed Step-by-Step Explanation:
* Default Next Hop Behavior in BGP:
* Locally Originated Routes (A): The next hop is set to the advertising router's interface IP address.
* Routes Received from EBGP (B): The next hop is not changed when these routes are advertised to IBGP peers. (This makes Option B false.)
* Routes Advertised to EBGP (C): The next hop is set to the interface IP address of the advertising router.
* Routes Advertised Between IBGP Peers (D): The next hop is not modified by default.
* Incorrect Statement:
* Option B is incorrect because the next hop of a non-labeled route received from an EBGP peer is not changed when it is advertised to IBGP peers.
