Abstract
The IPv6 VPN Provider Edge Router (6VPE) is used as a solution to overcome the security holes in its predecessor (6PE). Both methods allow ISPs to provide end-to-end IPv6 comiectivity over the legacy MPLS core networks. The former establishes tunnels between edge routers to carry IPv6 packet via the MPLS core routers. The later adds the feature of creating VPN for each customer so that the private customer traffic is not disseminated. However, as the MPLS replace the IP header with the labels the overall system performance is questionable in terms of connectivity and data security. Thus, the trade-off between these performance metrics will be evaluated in this paper using Monte Carlo methodology.
