04. Lab topology and devices preparation

Lab topology

We are using the two Juniper MX routers called fabric-01 (mx10-1) and fabric-02 (mx80-3).
There are directly connected between them (from their interface xe-0/0/0).

OpenConfig repository

The OpenConfig models are available in the Openconfig repository.

OpenConfig package installation on Juniper devices

• You first need to download the OpenConfig package from Juniper download website
• Then you need to install the OpenConfig package on the devices:

lab@fabric-02> request system software add xxxx

Check the Openconfig details on Juniper devices:

You can then check:

lab@fabric-02> show version detail | match openconfig
JUNOS Openconfig [0.0.0.3]

The Openconfig modules and the corresponding translation scripts are already installed on the two devices.

lab@fabric-01> show system yang package

Translation script status is enabled

The YANG modules, the equivalent YIN modules, and the translation scripts are stored into these directories:

lab@fabric-01> file list /opt/yang-pkg/junos-openconfig/yang
lab@fabric-01> file list /opt/yang-pkg/junos-openconfig/yin
lab@fabric-01> file list /opt/yang-pkg/junos-openconfig/translation/
