Please help me with thia design, i don't know how to move forward with this.
I need to assign ip addresses to the connections between the core devices and the edge devices. I want to have routed point to point links between the devices but i also want to run hsrp so traffic destined for the core devices would point to the hsrp address, likewise traffic head out towards the edge of the network.
Is this acheivable? I don't even know how to properly explain what I need but hopefully you get my drift.
Currently there is a /30 p2p routed link between the single core and edge device that exist. I am adding a further edge switch and core switch (both MLS) and I need to make this as resilient as possible.
Should I have all the interfaces between the core and edge in the same subnet - maybe a /28? How else will the edge see the core if for instance I have the core1 to core 2 connections plus their hsrp in a separate /29 address to the edge devices??
I also would like to implement some policy based routing on the edge switches so that routing to the firewalls and the encryption routers will be resilient.
Please help, any requests for clarification will be promptly responded to.
