In-band ZTP management in campus fabrics (EX4100-48MP, EX4100-24MP, EX4100-48P, EX4100-48T, EX4100-24P, EX4100-24T, EX4100-F-48P, EX4100-F-24P, EX4100-F-48T, EX4100-F-24T, EX4100-F-12P, EX4100-F-12T, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48P, EX4400-48T, EX4650, EX9204, EX9208, EX9214, MX304, QFX5120-32C, QFX5120-48T, QFX5120-48Y, and QFX5120-48YM)—Starting in Junos OS Release 24.2R1, you can simplify the provisioning process for campus fabrics. Already provisioned upstream devices, such as core and distribution devices, that are capable of detecting downstream Day 0 devices can provide Layer 3 connectivity. With Layer 3 connectivity, the downstream Day 0 devices can proceed with Secure ZTP.
To configure in-band ZTP management, enable the
in-band-ztpstatement at the[edit system services]hierarchy on your core and distribution devices. Optionally, your cloud controller can provide the in-band-ztp configuration as part of the provisioning process for your core and distribution devices.
