Routing is a design way to pass the data packet. User is assigns the path in a routing configuration. A significant role played by the router for providing the dynamic routing in the network. Structure and Configuration are different for each routing protocols. Next generation internet protocol IPv6 which provides large address space, simple header format. It is mainly effective and efficient routing. It is also ensure good quality of service and also provide security. Routing protocol (OSPFv3) in IPv6 network has been studied and implemented using ?cisco packet tracer?. ?Ping? the ping command is used to check the results. The small virtual network created in Cisco platform .It is also used to test the OSPFv3 protocol in the IPv6 network. This paper also contains step by step configuration and explanation in assigning of IPv6 address in routers and end devices. The receiving and sending the packet of data in a network is the responsibility of the internet protocol layer. It also contains the data analysis of packet forwarding through IPv6 on OSPFv3 in simulation mode of cisco packet virtual environment to make the decision eventually secure and faster protocol in IPv6 environment.

\section[{Introduction}]{Introduction}\par
he Internet is growing throughout the world, and different kinds of devices are becoming part of the internet every day. IP (Internet Protocol) is the most used routing protocol for communication over the network .The data packets are selecting the path of routing which mainly depends on the devices attached to the network. Packet destination address (IP) must be known from one device to another so that they can easily communicate with each other also wanted the neighboring devices information. Network topology studies the path for that region we can use OSPF technique. IPv4 and IPv6 are two categories of internet protocol. The IPv6 protocols represent an advance version of the IPv4 \hyperref[b12]{(Oliveira, De Sousa, et al. 2011}). IPv6 uses 128 bits addressing scheme which is more complicated than IPv4. IPv4 provides 32-bit addressing space in which 4.3 billion internet protocol address (Hinds,  {\ref Atojoko, et al. 2013)}. A study report shows that (10-15) \% IPv6 replaces IPv4 around the world after 25 years later (I.v. \hyperref[b9]{Beijnum. 2016)}  V. 
\section[{Topology Simulation for OSPFv3}]{Topology Simulation for OSPFv3}\par
Now, we considered the model of the network for OSPFv3 that contains three routers, two switches, four computers (mainly, end devices) for using the establish connection among routers. The automatic and connection between switch to end devices. The network model gives below:  6. Router OSPFv3 '1' the '1' gives the area 0 which same for all router in the same domain. In IPv6 router-id is manually set up for the domain and area specification. But it can be any number.\par

\section[{Exiting Configuration of ospfv3 with ipv6}]{Exiting Configuration of ospfv3 with ipv6}\par
The model of the network that is implemented and verified using 'ping' command from any pc's that attached to the router. Now, the result shows below are using the pc0 and pc1 through pinging the address to another. Now, show in the below:  
\section[{Data Collection}]{Data Collection}\par
Ping command is used to check the configuration results in different routing protocols. Fig. \hyperref[fig_6]{2} shows the small network model design for OSPFv3 in IPv6 protocol and packet transfer calculated for the time taken by it to travel from sender to receiver node. These data obtained by ping command and the traffic generator using the simulation for auto/capture/play button. It mainly shows the time to travel and reach the packets from source to destination nodes. Now Fig. \hyperref[fig_4]{12} shows the simulation mode of cisco packet tracer environment for OSPFv3 in IPv6 protocol.   
\section[{Data Analysis}]{Data Analysis}\par
The simulation process which indicates the impact of the traffic sent and received in the network. It generates through a ping command method from pc0 to  pc1 which shows the connectivity, justification, testing, and transfer of the packet from source to destination. It also verified the simulation and packet transfer time with the observed parameters is checked from pc0 and pc1 with constant delay and without constant delay which constructed from the simulation time. The graph shows the simulation time vary from node to node when a packet travels through the network and finally the IPv6 network finds out the performance of the routing protocol OSPFv3.

\section[{Conclusion}]{Conclusion}\par
This paper demonstrated that Cisco tracer could be used by network planners to select and to design various networks and optimal routing topology. In a network, routing is used to trace the path. In this paper, we used cisco packet tracer for implementing a routing protocol. We use OSPFv3 routing protocol in IPv6 network due to the usage and area of necessity though there are many different types of routing techniques. OSPFv3 are used for small and large enterprises and other business organization for IPv6 network environment. The time zone (second) in each station mainly packet take to travel one station to another, check the destination address to plot these generated time zone to show how fast data packet flows through a network of OSPFv3 in IPv6 environment with and without constant delay. It used for security, unlimited hop count, low overload, authentication. OSPFv3 uses area concepts which mainly eases management, route and packet traffic control.\begin{figure}[htbp]
