Alcatel-Lucent NRS II – Wide Area Network Services — Question 9

Which of the following statements regarding RSVP path messages on an Alcatel-Lucent SR is true?

Answer options

• A. The path message's IP header options field sets the router alert option.
• B. The IP header source address is the sender's egress interface address.
• C. The IP header destination address is the next-hop interface address.
• D. The IP header HOP object reflects the upstream router's egress interface address.

Correct answer: A

Explanation

The correct answer is A, as the path message's IP header options field indeed sets the router alert option, which is essential for RSVP functionality. Options B and C are incorrect because the source address does not represent the sender's egress interface and the destination address does not indicate the next-hop interface. Option D is also wrong since the HOP object does not reflect the upstream router's egress interface address.
