1. Initial BGP Setup

2. First Look at iBGP - In this scenario, we will modify the configuration you built in Scenario 1. No longer will we have a load-shared tunnel to the ISP router, but will have redundant enterprise routers that connect to a single provider router.

3. Simple Multihoming to Two ISPs - This scenario builds on Scenario 2. It introduces no new configuration commands, but simply has more routers so you can see the effects of the AS_PATH.
