Have not setup HSRP before but it doesn't seem challenging until you get to the physical connections which I can't find documented anywhere.
See Diagram for better understanding.
So my scenario is two headend routers running HSRP handing off one Cat-5e cable each to my 2 cisco routers which will be running HSRP on my end.
Do I need to place a switch between these two pairs of routers?
Can I plug these single connections for their two routers directly into my two routers? Will this allow for redundancy against all possible situations?
I know HSRP communicates via multicast but don't undestand exactly what requirements are needed to provide a "path" for this communication.
What is best practice here?
