You are using EBGP peering in an underlay IP fabric. Which two statements are correct in this scenario? (Choose two.)

Question

Options

• AEBGP peering requires an IGP protocol tor adjacency establishment.
• BEBGP peering does not require an IGP protocol tor adjacency establishment.

• B

• D

Explanation

Every leaf node has one peering session to every spine node: In an EBGP peering setup within an underlay IP fabric, each leaf node typically establishes a single EBGP session with each spine node. This is a common design for scalability, as it ensures that the leaf nodes can exchange routing information with all spine nodes directly. EBGP peering does not require an IGP protocol for adjacency establishment: EBGP (External BGP) peering in an underlay IP fabric does not require an IGP (Interior Gateway Protocol) such as OSPF or IS-IS to establish peering relationships. EBGP is used for establishing external routing between different ASes, and within a single AS, the peering is established directly between devices. This eliminates the need for an IGP for the actual EBGP session.
