Describes how the generic bootstrap configuration initializes a device and integrates it into the overlay network. This process ensures secure authentication and automated connectivity for WAN edge devices.
Summary
The process involves the following key components:
-
SD-WAN Manager: Orchestrates device authentication and template management.
-
Cisco IOS XE Catalyst SD-WAN device: The WAN edge device being initialized.
-
SD-WAN Validator: Facilitates initial device discovery and registration.
-
SD-WAN Controller: Manages control connections and overlay network membership.
Workflow
These stages describe the lifecycle of a generic bootstrap configuration from initial setup to network integration.
-
Initial configuration and device reset.
-
Select the interface serving as the VPN 0 (WAN) interface on the Cisco IOS XE Catalyst SD-WAN device during configuration generation on SD-WAN Manager .
-
Copy the configuration file to the device bootflash and reset the device to initialize the bootstrap settings.
-
-
Network discovery and authentication.
-
The bootstrap configuration enables a DHCP client on the VPN 0 interface to acquire network details.
-
The device connects to the SD-WAN Validator and appears as an unclaimed WAN edge device.
-
Upon claiming the device on SD-WAN Manager , the system authenticates the device using its installed certificate.
-
-
Template attachment and network integration.
-
Associate and deploy a configuration group containing the system IP and site ID to the device.
-
The device establishes control connections to SD-WAN Control Components to join the overlay network.
