IPv6 (Internet Protocol version 6) is a revision of the Internet Protocol (IP) developed by the Internet Engineering Task Force (IETF). IPv6 is intended to succeed IPv4.

IPv6 implements a new addressing system that allows for far more addresses to be assigned than with Ipv4.

Multiprotocol Label Switching (MPLS) is deployed by many service providers for establishing their backbone networks.

The Cisco implementation of IPv6 provider edge router over MPLS is called 6PE,and it enables IPv6 sites to communicate with each other over an MPLS IPv4 core network using MPLS label switched paths.

Project- SeminarDate: 22/03/2014 DRK INSTITUTE OF SCIENCE & TECHNOLOGY Department of Electronics & Communication Engineering IMPLEMENTATION OF ISP MPLS BACKBONE NETWORK ON IPV6 USING 6PE ROUTERS Routing and Routing Protocols The three methods by which a router can add IP routes to its routing table are: 1. Static routes – Adding a route due to the engineer adding an ip route command to the router’s configuration. 2. Dynamic routing protocols – Adding routes using routing protocols, which cause routers to dynamically exchange routing information with other routers.

Project- SeminarDate: 22/03/2014 DRK INSTITUTE OF SCIENCE & TECHNOLOGY Department of Electronics & Communication Engineering IMPLEMENTATION OF ISP MPLS BACKBONE NETWORK ON IPV6 USING 6PE ROUTERS ROUTER BASICS Basic Concepts The router decides where to forward the packet base on the routing table. To route packets, routers must have routes in their IP routing tables. Each entry in a router’s IP routing table has important information, including the following vital information: 1. The destination subnet (subnet number and subnet mask. 2. Directions that tell the router to what other router or host to send the packet next (outgoing interface and next-hop router).

Link State Database: Similar in all routers. Formed after each router floods its neighbor database. Routing table: Each router builds this table by using SPF technology. It gives the shortest path to all the routers in the AS.

Project- SeminarDate: 22/03/2014 DRK INSTITUTE OF SCIENCE & TECHNOLOGY Department of Electronics & Communication Engineering IMPLEMENTATION OF ISP MPLS BACKBONE NETWORK ON IPV6 USING 6PE ROUTERS OSPF Features of OSPF: 1. The OSPF protocol is a link state Protocol that handles routing for IP traffic. 2. Open Shortest Path First (OSPF) uses the Shortest Path First (SPF) algorithm, to provide a loop-free topology. 3. Open Shortest Path First (OSPF) provides fast convergence with triggered, incremental updates via Link State Advertisements (LSAs). 4. Open Shortest Path First (OSPF) is a classless protocol and allows for a hierarchical design with VLSM and route summarization. 5. The two important concepts in case of OSPF are Autonomous Systems and Areas.
