Abstract— The development of company's business area will
have implications for the development of computer network
infrastructure as a means of exchanging data and information
between regions. As a company that continues to develop its
business area, PT. Timur Raya Lestari requires a computer
network infrastructure that is adaptive to the development of the
number of branch offices. The company's computer network
currently uses the Static Routing method in determining the
interconnection path between Routers connecting the head office
and branch offices. The development of a dynamic company must
be accompanied by the development of a dynamic network
infrastructure as well. Development of a network infrastructure
that continues to develop requires Dynamic Routing Protocol. In
this study, it was simulated the use of EIGRP as Dynamic Routing
Protocol for PT. Timur Raya Lestari. From the simulation results
using Cisco Packet Tracer software, it can be seen that there is a
stable interconnection, both for existing networks plan and
planning for adding networks on new branch offices.
