Abstract
U radu je bilo potrebno navesti pregled značajki BGP (engl. Border Gateway Protocol) usmjerivačkog protokola te analizirati primjenu BGP protokola u virtualnim privatnim mrežama (VPN, engl. Virtual Private Network). Značajke BGP protokola su višeprotokolna proširenja koja olakšavaju rad pri definiranju dostupnosti određenih usmjerivača. Primjena BGP protokola u VPN zasniva se na distribuciji ruta. Prilikom uspostave BGP-a uspostavlja se sjednica između rubnih usmjerivača jezgrene mreže. Analizom mrežnog prometa vidljive su BGP poruke koje se razmjenjuju nakon pokrenute sjednice. Osim BGP poruka također s mogu vidjeti i BGP atributi puta što je pokazano prilikom konfiguracije topologije u GNS3 simulatoru za prikaz uporabe BGP protokola u VPN-u. Prilikom provjere dostupnosti odredišta također se može provjeriti enkapsulacija IP zaglavlja unutar MPLS oznaka. Glavni preduvjeti za postavljanje BGP unutar VPN-a su postavljanje MPLS jezgrene mreže te VRF puteva između CE usmjerivača.

Parallel abstract (English)
In this paper, it was necessary to review the BGP routing protocol features and analyze the application of BGP protocols in virtual private networks. BGP protocols feature multi protocols that make it easier to work on defining the availability of certain routers. The application of the BGP protocol to the VPN is located in the route distribution. When establishing a BGP, a session is established between the peripheral router cores. Analyzing network traffic shows BGP messages that are exchanged after the sessions are started. In addition to the BGP message, you can also see the BGP path attributes shown in the topology configuration in the GNS3 simulator to display the BGP protocol usage in the VPN. When checking the availability of the destination, it is also possible to check the encapsulation of the IP header within the MPLS tag. The main prerequisites for setting up BGP within the VPN are setting the MPLS core network and VRF routes between the CE routers.
