This lab is based on a lab I found on one of the forums, and in this lab we will use GNS3 to create an advanced lab consisting of 12 inter connected Cisco 3640 IOS based routers. We will use this lab to gain a better understanding of how to configure MPLS VPNs. In addition to these technologies we will review basic router configuration along with some other technologies such as OSPF, BGP, NAT, IPSEC and GRE.

This free GNS3 lab is an effort to provide a better understanding of Multiprotocol Label Switching (MPLS) and how to configure it on Cisco IOS routers.
In this free GNS3 Lab you will be configuring EIGRP, OSPF, IBGP and BGP across multiple autonomous systems. You will also configure Point-to-Point and Point-to-Multipoint Frame-Relay. For this lab we are using an old INE topology consists of 9 routers and 4 level 3 switches. Routers with switching modules install have been substituted for level 3 switches as GNS3 does not support level 3 switches.
Many of my readers have posted that Cisco’s Packet Tracer does not support BGP (Border Gateway Protocol). This is not the case, in the latest version of Packet Tracer 5.3.2 there is limited support for BGP. The most limiting lack in support is Internal BGP (iBGP) and is currently not supported in the latest version of Packet Tracer. This does not allow the user to create neighbors between routers within the same autonomous systems. Although even with this limitation there is sufficient support to allow the CCNA, CCNP student to gain an understanding of this complex routing protocol and to learn how to use the following supported command within Packet tracer.
