Abstract
Proposed herein are techniques to address critical risks in modern networking associated with the dependency between overlay and underlay infrastructures. By implementing a mechanism to exclude specific underlay prefixes from overlay routing via a Routing Exclusion Base (REB) and exporting this information to a Routing Information Base (RIB), the techniques proposed herein prevent recursive routing errors, which can lead to service outages and impact business operations. This approach simplifies network management, reduces operational overhead, and diminishes reliance on specialized expertise, providing a universal solution applicable to various routing protocols, such as Multiprotocol Label Switching (MPLS) Virtual Private Network (VPN), Segment Routing Traffic Engineering (SR-TE), and others.
