What is the manual model of underlay?
It is configured and managed manually (such as with a CLI or an API) rather than through Cisco DNA Center
What are 2 advantages of the manual model of underlay?
- It allows customization of the network to fit any special design requirements (such as changing the IGP to OSPF)
- It allows SD-Access to run on the top of a legacy (or third-party) IP-based network
What is the Automated Model of underlay?
It is configured and managed by the Cisco DNA Center LAN Automation feature
What does the Cisco DNA Center LAN Automation feature do when used to configure the underlay network?
- Creates an IS-IS routed access campus design
- Uses the Cisco Network Plug and Play features to deploy both unicast and multicast routing configuration
What are 3 advantages of using the Automated model of underlay?
- Eliminates misconfigurations
- Reduces the complexity of the network underlay
- Greatly simplifies and speeds the building of the network underlay.
What is a disadvantage of using the Automated model of underlay?
It does not allow manual customization for special design requirements.
What are 3 things that the Overlay Network (SD-Access Fabric) provides?
- Provides policy-based network segmentation
- Host mobility for wired and wireless hosts
- Enhanced security beyond the normal switching and routing capabilities of a traditional network
What type of model is the Overlay Network, manual or automated?
Always fully automated regardless of what model is used on the underlay network
What 2 things does the Overlay network include?
- All necessary overlay control plane protocols and addressing
- All global configurations associated with operation of the SD-Access fabric.
If the Overlay is manually configured without the use of Cisco DNA Center what is it called?
A campus fabric solution (not SD-Access)
