Abstract
The use of internet connections to develop Virtual Private Network (VPN) lines in companies has been massively applied. An example is the use of Dynamic Multipoint VPN (DMVPN) technology from Cisco, which can connect Spoke or branch offices through HUB or data centers. Besides requiring a secure network, companies also need high network availability. One of them is by using the redundancy method in order to minimize downtime when device damage occurs. In this research, the spoke router will apply two redundancy methods by Cisco, which are Hot Standby Router Protocol (HSRP) and Gateway Load Balancing (GLBP). This research aims to compare the QoS performances and downtime between the two protocols in order to discover the suitable method for DMVPN networks at branch offices. The test scenario is conducted on the GNS-3 simulator using the File Trasnfer Protocol (FTP) service. The obtained test result shows that the HSRP throughput value is smaller from the GLBP with a difference of 0.20%, the increase in the average delay of the HSRP is smaller from the GLBP with a difference of 1.07%. The HSRP data transfer time is faster than GLBP with a difference of 1.49%, and HSRP downtime is 4.13% faster than GLBP. The conclusion is that a suitable redundancy solution for spoke router using the HSRP method

Summary
Saat ini banyak perusahaan yang memanfaatkan teknologi informasi dalam menjalankan proses bisnisnya, terutama dengan menggunakan internet untuk membuat jaringan komputer agar perangkat dapat saling berkomunikasi dan berbagi data. Cisco memiliki metode yang dapat digunakan sebagai solusi redundansi dan mengurangi downtime, yaitu HSRP dan GLBP. Pemilihan kedua metode tersebut dikarenakan perangkat yang digunakan saat ini merupakan router Cisco, sehingga akan lebih maksimal jika menggunakan protokol milik Cisco sendiri. Jaringan cabang PT XYZ akan dirancang menggunakan kedua metode redundansi ini dengan kondisi dua router spoke yang aktif. Penelitian [6] memberikan hasil kinerja VRRP pada topologi Star dengan routing EIGRP lebih baik dibanding HSRP dan GLBP karena hasil delay tidak mengalami kenaikan saat kondisi jaringan terputus. Maka penelitian ini akan membandingkan kinerja dari kedua metode redundasi milik Cisco pada jaringan DMVPN. Sehingga hasil penelitian ini dapat memberikan solusi metode redundansi yang sesuai untuk router spoke
