Bootstrapping methods

The following bootstrapping methods are supported.

• Use DHCP option 143 (IPv4) or 163 (IPv6), as described in RFC 8572. Optionally, the operator can obtain the specific node URI (server and directory) by providing the DHCP server option 61 for the DHCP server, which in turn provides option 67 for the file directory, or option 143 (IPv4) or 163 (IPv6) with the server IP and file directory information. In this case, the TLS certificates, trust anchors, and keys must be installed on the node at the operator premises.
• Copy the following information to the CF:
  • redirect information for the bootstrap server
  • TLS certificates and trust anchors, and private keys
  • onboarding information
• Use ZTP to provide the following information to the node:
  • redirect information for the bootstrap server
  • TLS certificates and trust anchors, and private keys
  • onboarding information
• Redirect the node from the first bootstrap server to consecutive bootstrap servers. The bootstrap server can provide the node with additional redirect information in a secure encrypted manner. The redirect and onboarding information are provided in the conveyed information file.
  • redirect information to another bootstrap server
  • required TLS certificates and trust anchors, and private keys
  • onboarding information
