This alternative concerns bgp peering and route policy boundaries; its associated risk is: An established BGP session does not by itself prove that correct prefixes are advertised or accepted without leaks. The observed case A replacement optic negotiates link but reports rising receive errors during peak traffic because the path budget was never measured requires the more specific rack transceiver compatibility and link budget control.
