In this Free CCNP GNS3 Lab we are going to use GNS3 to create simple BGP network consisting of four Cisco routers and a single switch to demonstrate how we can use BGP’s weight attribute to influence routing out of an autonomous system (AS).
In this Free CCNP Lab you will create a multihomed ISP connectivity solution and contracted with two ISPs for Internet connectivity with fault tolerance. Because you are connecting to two different service providers, you must configure BGP, which runs between the boundary router and the two ISP routers.
