What must a BGP Speaker do to transmit routing information to other IBGP peers?

• A. Establish IBGP connections with all other IBGP peers
• B. Form an IBGP fully meshed connection with only one peer
• C. Establish connections with external BGP peers
• D. Send routing information without establishing connections

Answer: (A)

A BGP speaker must establish IBGP connections with all other IBGP peers to transmit routing information effectively. In the context of BGP (Border Gateway Protocol), IBGP (Internal BGP) is used within an Autonomous System (AS) to ensure that all BGP speakers within the AS are informed about routing information to other networks. By establishing IBGP connections with all peers, a BGP speaker ensures that routing information is consistently and reliably shared across the entire AS. This full interconnection is necessary because IBGP does not propagate routing updates to other IBGP peers unless a direct connection exists. Therefore, each BGP speaker must form a peer-to-peer relationship with all other IBGP speakers to facilitate the exchange of routing information. Establishing such connections creates a fully meshed configuration or a hub-and-spoke model, depending on the network design, but the critical requirement is that each speaker communicates directly with every other. This prevents routing loops and maintains the stability of the BGP routing process within the AS. In summary, for effective routing information sharing, it's crucial for a BGP speaker to set up connections with all other IBGP peers.
