Day One: Configuring Junos Policies and Firewall Filters
Pairing routing policy and firewall filters may, at first glance, seem like an odd combination for a routing book, after all, filters are for security and policy is about manipulating route attributes and readvertisement.
While route advertisement decisions can impact security, these two topics are more logically bundled into a single book because of the high degree of similarity in their Junos configuration syntax. Knowing one simply helps you learn the other, and given that both are critically important topics in modern IP networks, their synergy should not be ignored.
Day One: Configuring Junos Policies and Firewall Filters shows how the savvy network administrator can make unified and robust efficiencies using two similar tools from their Junos toolbox.
“Jack Parks provides clear, concise descriptions and configuration examples to illustrate basic concepts as well as complex examples that demystify policy and filter operations and capabilities that are not widely understood. this is your chance to finally understand why that nested firewall or Boolean grouped policy did not behave as you expected.” Harry Reynolds, Author, Senior Test Engineer, Juniper Networks
