JUNOS Control plane protection
This Day One Book provides a good coverage of Control plane protection firewall filters. Or you can use Juniper MX Series book – same material there.
Also take a look at QFX Security Feature Guide, Firewall Filters Configuration Guide and User and Access Management Feature Guide.
All of this are not the core topics of JNCIE-DC lab, so I don’t expect any really complex tasks in this chapter – just basic stuff.
Just ensure you have basic understanding how to configure and apply CoPP firewall filter and know how to apply Role-base access control in JUNOS.
