=====Cisco Books - CCIE Bridging the Gap: Chapter 10 - Lab 10-1=====
=====Parameters=====
This lab has the following parameters:
* RIPv2 as the underlay, to provide a route between loopbacks.
* iBGP as the overlay to share routes between four routers.
* The loopback addresses are used as the peering between the iBGP neighbors.
* BGP peer groups are used for all neighbors.
* BGP neighbors have authentication configured.
