Abstract
PT. KAI Palembang is a branch of PT. Kereta Api Indonesia (KAI) Persero located in South Sumatra Province, where PT. KAI Persero is an Indonesian State-Owned Enterprise that organizes railway transportation which provide services including passenger and goods transportation. PT. KAI Palembang has a computer network connected to PT. KAI Persero central is located in Jakarta. Now, PT. KAI Palembang is trying to improve computer network security, where one of them is limiting the access of users who connected to PT. KAI Palembang computer network. This can be done by implementing Access Control Lists (ACLs) and Frame Relay on PT. KAI Palembang computer network. In this research used the Network Development Life Cycle (NDLC) method which has several stages, namely Analysis, Design, Simulation Prototyping, Implementation, Monitoring and Management. This research method is used because the results of this research will be displayed in the Cisco packet tracer simulator. In addition, the results of this research were tested using a ping test between computers to show that the ACLs design had been running well.

In this research, Enhanced Interior Gateway Routing Protocol (EIGRP) is used, which is a cisco routing protocol that works on cisco routers and on internal route processors that found on layer core switches and cisco distribution layer switches and EIGRP is a classes and enhaced distance vector protocol [6]
Summary
KAI Persero central computer network located in Jakarta, where the two networks were connected using a router device. A router is a device that will pass IP packets from a network to another network using the addressing and certain protocol method to pass that data packet [1]. Routing needs to be done to the router device so that it can be used, where routing is the process of directing data packets to get the destination from one location to another [4]. In order to implement both of these technologies, so necessary to build a Virtual Local Area Network (VLAN) by utilizing router and switch, where VLAN are logical groupings of users and network resources that are connected to determined ports on a switch administratively [11]. The main purpose of the cisco packet tracer is to provide tools for participants and instructors to be able to understand the principles of computer networking and build skills in the network configuration field that use cisco [13]
