We are preparing a design for a customer to upgrade there outdated network infrastructure ( 900+ nodes) and this primarily includes deploying Cisco SDA and DNAC.
The current design is fairly very simple and straightforward. It consists of two 6509 Cisco switches as Collapsed core and Edge Switches are mixed of 2960s and 3500s
Core switches are configured as HSRP Active/Standby and Active Core switch is root bridge for all vlans.
VLANs are segmented as per department wise and all vlans are configured and spanned through out all switches.
Servers are connected to dedicated access switches with an uplink to core switches
We need to know
- What licensing is required on Cat 9k switches
- Which switch models we suppose to buy ?
- How to make proper subnet sizing ?
- What is fusion router ? Do we need in our case ?
- Where to place and connect existing servers and firewall to fabric ?
- Is it mandatory to have ISE with DNAC ?
Any leads on this would really help us a lot.
