Example Concept: BGP routing leaks occur when prefixes are advertised to unintended networks, potentially causing traffic misdirection or network instability. Detection methods include using BGP monitoring tools like BGPmon or RIPE RIS to track route announcements, implementing RPKI (Resource Public Key Infrastructure) to validate route origins, and configuring BGP communities and route maps to enforce strict routing policies. These measures help ensure that only authorized prefixes are advertised to the correct peers.
