Abstract :
Sending packets in a router network requires a routing protocol to determine
the best path. One of the routing protocols that routers can use is EIGRP with the
DUAL concept which has a feasible successor facility. EIGRP allows routers to
perform faster-routing processes for path recovery in case of a packet delivery failure.
This study aims to analyze the effect of using a feasible successor on the EIGRP routing
protocol. The research uses VirtualBox as a hypervisor to run host os and GNS3 as
network emulator. This study aims to determine the effect of using a feasible successor
by linking down the main line when the client PC sends packets to the PC server. The
test is measured based on the convergence time of delay, jitter, packet loss, and
throughput. The results of the convergence test on the feasible successor path
experience a faster time when sending ICMP packets of 128 Bytes with a convergence
time of 35.7904 ms. In the packet loss parameter when testing the convergence time,
the feasible successor path gets a value of 6.1947 % when sending packets of 1440
Bytes. The two path scenarios tested in the delay parameter got values below 150 ms
according to the TIPHON standard. In the jitter parameter, the two path scenarios tested
got values below 0 ms with a very good category according to the TIPHON standard.
In the throughput parameter, the two path scenarios tested are categorized as very
suitable for the TIPHON category because the available bandwidth values are only
scaled, considering the limitations of GNS3.
