Your ISP is announcing a default route to both R1 and R2. You want your network routers to forward all Internet traffic through the R1 device.
Which BGP attribute would you use?
To ensure that all Internet traffic is directed through R1, the local preference BGP attribute should be used. Local preference is an attribute that influences the outbound traffic from an Autonomous System (AS). By setting a higher local preference on the route received via R1 compared to the route received via R2, the routers within the AS will prefer the path through R1 for outgoing traffic. This allows you to control the exit point for specific traffic within your network, making R1 the primary route for all Internet traffic.
C. local preference
Local Preference for prefix received from other BGP Peer
