= HARDWARE =

*BORDERS - 7206VXR-NPE-G2
*CORE/ACCESS - 3750G (Stack)


= ROUTING INFORMATION =

* BGP between borders and provider (receiving full routes)
* BGP between border1 and border2 (receiving full routes)
* OSPF on L3 links between borders and core/access
	-core/access redistribute static and connected subnets
	-borders redistribute connected subnets & default-information originate always


* Additional Note, Provider B is directly connected to Provider A (the two isp's peer with eachother)
