Abstract: Today several organizations are in a process to adopt IPv6 addressing scheme. Since IPv6 is not backward compatible with IPv4, both IPv4 and IPv6 are going to work in parallel till IPv6 is fully deployed .Security in IPv6 is mandatory, but in IPv4 security scheme is optional. IPv6 packets are travelling through IPv4 network in transition mechanism. The IPv6 packet faces several security threats while it travels through IPv4 network. The transition remains an issue today for many enterprises which is a tedious and error prone task for network administrators. Routing protocols route the packet with their own metrics. The network administrator could not implement his own routing methodology in a routing process.In this project we are taking IPv6 network in GNS3 simulation tool and implement the IPSec scheme. Unauthorized routers are introduced in our network and we have to ensure that services for them are denied by our network routers. In the same network we are implementing the Policy Based Routing (PBR). Routers normally forward packet to destination addresses based on information in their routing tables. By using policy based routing we can implement policies that selectively cause packets to take different paths based on source address, protocol types or application types. Therefore PBR overrides the routers normal routing procedures. By implementing both the schemes in our IPv6 network, the IP packets are delivered safely and also take the path as desired by network administrator.
