Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 580

The MPLS LDP autoconfiguration feature allows you to enable LDP on every interface that is associated with an IGP instance. Which of the following Interior Gateway Protocols support this? (Choose two.)

Answer options

• A. OSPF
• B. IS-IS
• C. BGP
• D. RIP
• E. EIGRP

Correct answer: A, B

Explanation

OSPF and IS-IS are the only Interior Gateway Protocols that support the MPLS LDP autoconfiguration feature, enabling LDP on all interfaces associated with their IGP instance. BGP is a Border Gateway Protocol and does not fall under the category of Interior Gateway Protocols, while RIP and EIGRP do not support this specific feature.
