The purpose of GROW is to consider the operational problems associated with the Internet Protocol (IP) global routing systems, including but not limited to default-free zone routing table growth, effects of the interactions between interior and exterior routing protocols, the effect of address allocation policies, or practices on the global routing system. Where appropriate, GROW documents the operational aspects of measurement, monitoring, policy, operational global routing system security, VPN infrastructures, or safe default behavior of global IP routing protocol implementations and deployments. SIDR operations related work will occur in SIDROPS GROW will also advise various working groups, mainly IDR and SIDROPS, with respect to whether it is addressing the relevant operational and routing security requirements of Internet-connected networks, and where appropriate, suggest course corrections. Goals: ------ Provide stewardship and maintenance for the BGP Monitoring Protocol (BMP) Provide stewardship and maintenance for the Multi-Threaded Routing Toolkit (MRT) Routing Information Export Format Document Best Current Practices for operations of the Internet global routing system. Document the operational aspects of securing the Internet routing system, and provide recommendations to other WGs. Provide documentation to assist in preventing malpractice in the global routing system.
