Here's the scenario:
1. Two Catalyst 4507's configured for redundancy using HSRP and EIGRP for routing.
2. Switch A has the highest priority and is active.
3. Switch B is in standby mode, but Internet connectivity is provided through a 3845 router connected to this switch.
Here's the question:
How do I configure a single 3845 router to provide connectivity to the internet in case Switch B goes offline?
