AUTOCONFIGURATION FUNCTION

AUTOINSTALLATION

• Autoinstallation DHCP/BOOTP client supports options:

✓ Router-address (option 3)

✓ DHCP Server ip-address (option 54)

✓ tftp-server ip-address (option 150)

✓ Option 60 class ID (Identifies type of platform)

✓ Boot file Name (option 67; relative path)

• Autoinstallation function is part of the factory default configuration. Router sends BootP discoveries on active physical ports for 5 min. If no valid DHCP received a system reboot is required to reinitiate an auto installation.

• Options to run script from USB when booted for operational customization - example establish SSH to management server


ZTD USE CASE WITH MPLS IN THE ACCESS

Decoupling MPLS Data from ZTD Management (OAM) Plane

MPLS DATA and SERVICE PLANE

Layer 2 OAM and MANAGEMENT PLANE

ZTD Management Plane is required to provide L2 connectivity between any newly connected node and AGN. There two options:

✓ Use a dedicated VLAN shared across access ring (IEEE802.3 bridging)

✓ Enable Layer 2 service on top of the provisioned MPLS infrastructure
