Abstract
To support qualified IT operations, recently many companies have hired more than 1 (one) communication link as a redundancy and to improve High Availability or the availability of their network systems. One method to improve high availability of multi router networks (links) is to use Gateway Load Balance Protocol (GLBP) which is a protocol that works on OSI layer 3. Where the GLBP function is to divide the traffic load and as a failover function when one router / link is damaged. Gateway Load Balancing Protocol (GLBP) itself is born from the concept of load balancing, a concept that is useful for dividing / balancing loads or loads on multiple links to the same remote network. That way the network link will not be disturbed if there is damage caused by one of the routers.This thesis describes the concept of GLBP by using the weight method where network simulation tools use GNS3 software. The results obtained from the simulation with GLBP weight method sharing the router data load is determined by the weight value given to each router. Where Comparison of Weight Values given to the Router will determine the number of data packets transmitted to the router.

PENDAHULUAN Sistem Information Technology (IT) saat ini memegang peranan penting dalam kehidupan kita sehari-hari, karena dengan sistem IT memudahkan proses komunikasi secara efektif dan efisien walaupun dipisahkan oleh jarak dan waktu

Summary
GLBP memungkinkan untuk menginterupsi gateway virtual yang aktif dengan backup yang mempunyai higherpriority. Dengan metode GLBP, 2 gateway fisik yang ada pada interface ethernet LAN RSA1 dan RSA2 dikonversi menjadi satu gateway virtual dengan IP 192.168.20.100 yang dijadikan sebagai gateway PC. Pada jurnal ini nilai weight yang digunakan adalah 100 pada router RSA2 yang merupkan nilai default (jika tidak dikonfigur) Cisco dan nilai 200 pada router RSA1 untuk memberikan perbandingan nilai 2:1 pada topologi yang bertujuan sebagai pembagi beban. Pada simulasi ini nilai weight yang digunakan sebagai nilai perbandingan antara router RSA1 dan RSA2 yang nantinya akan menentukan jumlah packet data yang akan diteruskan sesuai nilai weight yang disetting. 2. Host Identifier / HostID atau Host address (alamat host) yang digunakan khusus untuk mengidentifikasikan alamat host di dalam jaringan
