Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 213

What is an MPLS LDP targeted session?

Answer options

• A. LDP session established by exchanging multicast hello packets
• B. LDP session established between LSRs by exchanging TCP hello packets
• C. session between neighbors that are connected no more than one hop away
• D. label distribution session between non-directly connected neighbors

Correct answer: D

Explanation

The correct answer, D, describes a targeted session in MPLS LDP, which allows label distribution between LSRs that do not share a direct link. Option A is incorrect because multicast hello packets are not used for targeted sessions. Option B is wrong as it refers to regular LDP sessions established via TCP, while C limits the definition to directly connected neighbors, which does not apply to targeted sessions.
