Juniper NFX250 - Example: Configuring Service Chaining Using SR-IOV on NFX250 Network Services Platform

user@jdm# set virtual-network-functions VM1 interfaces eth2 mapping vlan members vlan1
user@jdm# set virtual-network-functions VM1 interfaces eth3 mapping vlan members
glue-vlan
3. Similarly bring up VM2 with one interface with one interface mapped to VLAN2, and
the second interface mapped to the same glue-vlan.
user@jdm# set virtual-network-functionsVM2 interfaceseth2 mapping vlan members vlan2
user@jdm# set virtual-network-functions VM2 interfaces eth3 mapping vlan members
glue-vlan
4. Finally, configure the IP addresses and static routes for each interface of the VMs
as shown in Figure 14 on page 156.

Requirements
This example uses the following hardware and software components:
•
NFX250 running Junos OS Release 15.1X53-D45
Before you configure service chaining, be sure you have:
•
Installed and launched the relevant VNFs
Overview
Service chaining on a device running the disaggregated Junos OS allows multiple services,
or virtual network functions (VNFs), to be applied to traffic as it flows through the device.
This example explains how to configure the various layers of the device to enable traffic
to enter the device, flow through two service VNFs, and exit the device.
