Example: Configure NFX250-S2 as a Compute Server to Support Virtual Network Functions
Overview
This example configuration provisions the NFX250-S2 device as a compute server to support Virtual Network Functions (VNFs) as its main functionality.
The configuration provisions the basic NFX250-S2 requirements and provisions a single VNF for the PON Controller KVM image to be installed.
Modification to the IP addresses should be made that is appropriate for your individual deployment.
This example configuration provisions four of the Gigabit Ethernet copper interface ports to support the Layer 2 PON management control plane connections to external ACX routers with installed 10GbE PON OLT transceivers. It also provisions the four other Gigabit Ethernet copper interface ports to support the Layer 3 PON management control plane connection to the MicroClimateTM Management System database.
Note:
The configuration excerpt does not show the necessary user credential configuration information for a working system. The deployed system should have the configuration parameters set correctly.
The deployment configuration sets the NFX250-S2 device in compute mode and disables most NFX250-S2 Junos functionality, so that the system can be used as a VM host server.
Configuration
CLI Quick Configuration
To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.
