What happens when the peer default-mute-advertise command is executed on a BGP router?

• A. An inactive default route is generated but not delivered to the IP routing table
• B. An active default route is generated and delivered to the IP routing table
• C. No default route is generated in the local BGP routing table
• D. A default route is generated, but delivery depends on selection

Answer: (C)

When the peer default-mute-advertise command is executed on a BGP router, it disables the advertisement of default routes to its BGP peers. This command ensures that no default route is propagated into the local BGP routing table. The implication of this is that while the router may have a default route configured, it will not share this information with its BGP neighbors. In the context of BGP, advertisements of routes, including default routes, are crucial for dynamic routing operations. By using the peer default-mute-advertise command, network administrators can control which routes are shared, thereby preventing unnecessary or unintended routing information from being sent to peers. This can be particularly important in complex network designs where preserving the integrity of route information is essential. The other answers imply different behaviors regarding the generation and delivery of default routes, which do not align with the action enforced by the peer default-mute-advertise command. Hence, the selected choice accurately reflects the command's purpose and effect in the BGP routing process.
