Abstract
Nowadays Internet access across the globe is very crucial because of the huge size of useful data
that the Internet stores. This stimulates most ISPs to choose a reliable routing protocol in order to
preserve the security and guarantee of customer’s data on the Internet. By multi-homing a network
using BGP, a more control of balancing the traffic load and achieving redundancy becomes
possible. This will enhance network performance, quality throughput and better routing policies
on the Internet. Single-homed Internet communication link between networks’ Internet service
provider does not inspire with confidence because of excessive traffic and device or human error
that may arise. We use BGP because of its ability to choose the best path to a destination
particularly in a Multihoming environment. Our simulation results are achieved using GNS3
emulator and Wireshark network analyser. We carried out two simulations to run BGP
Multihoming to the same service provider and to different service provider. In both scenarios we
run the simulations in failover mode and in load-shearing mode. Simulation results show that BGP
Multihoming to different service providers provides failover to ISP networks. For a home and
enterprise network to have a certain level of failover or redundancy there is a need to employ the
use of BGP Multihoming to different service provider.
