Route creation influence on DMVPN QoS

Dynamic Multipoint IPsec VPNs (DMVPN) is IPsec VPN solution in Cisco IOS Software. This paper discusses QoS assurance in DMVPN spoke-to-spoke deployment, when using different routing protocols. Investigation of tunnel creation influence to multiple flow packets' delay in spoke-to-spoke connection by means of OPNET MODELER 10.5 was done here. The performance analysis made, allowed us to ascertain, which of routing protocols, used for DMVPN connection ensures the least delay value. It is determined that the least one was obtained when using RIP (Routing Information Protocol) and EIGRP (Interior Gateway Routing Protocol) were applied when establishing the route.
