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.

These labs are dedicated to understanding and configuring OSPF. The lab consist of four separate labs each lab building on the previous OSPF topology covering topic such as OSPF backbone area, Stubby, NSSA (Not So Stubby Area), and Totally Stubby areas, Virtual Link areas, OSPF over Frame-Relay, and redistribution of external network into an OSPF area.

In this Free Cisco Lab Packet Tracer activity we will be troubleshooting route redistribution between Open Shortest Path First (OSPF), Enhanced Inter Gateway Routing Protocol (EIGRP), Routing Information Protocol (RIP) and static routing protocols.
In This Free Cisco Lab we will configure Open Shortest Path First (OSPF) authentication using MD5 authentication to allow the authenticate OSPF neighbors. You can enable authentication in OSPF in order to exchange routing update information in a secure manner. OSPF authentication can be implemented in one of three methods.
