Orcid-0009-0005-2339-0878 Abstract: Problems such as combining two architectures in infrastructures are discussed in the paper. MPLS (Multiprotocol Label Switching), VPN (Virtual Private Network) and BSG (Border Gateway Protocol) risk analysis are presented, which can be beneficial for the modern research world. Keywords: Security, scalability, topology, optimization
