Posted by: admin  :  Category: BGP, CCIE, CCNP, GNS3 Dynamips, OSPF

MPLSandBGP-Advanced-1

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.
