Edge Network Design, Dual Connections

Hey, Im building a new network datacenter…dual everything(physically)

Is it a good idea to setup redundant connections(in RED) from the routers to each edge switch(there in a stack)?  If so, would you use port-channel or bridge from the router to the switch-stack?

Thanks

You should do point to point layer 3 connections between them. Assign a /30 network for each link between the stack and said router.

On the switch stack you would just create a routed port for each connection leading to each router. Asssign that port to a /30 and the router port to that /30 subnet. Do the same for the other connection to the other router, just on a different /30 subnet.

If I use the /30s..  Would it be internal addresses or external..  Also normally  I would have the same IPs inside the router connected to the firewall layer, normally my bgp IPs ...  Should I just have my external bgp IPs on my firewall layer...and do a private IPs for the middle switch to router inside?  Just trying to rap my head around it.
