Day One: Juniper Ambassadors’ Cookbook 2017

The Juniper Ambassadors take on some of the top support issues and provide clear-cut solutions and frank discussions on how to keep things running in their new Day One cookbook. The recipes provide quick and tested solutions to everyday networking administration issues.

“Day One: Juniper Ambassadors Cookbook 2017 covers several complex networking problems and solutions, working with technologies such as EVPN, VXLAN, OSPF sham links, centralized route reflectors, scripted automation with Python, segment routing, and BGP flowspec. Using Junos OS configuration stanzas and command line output analysis, each recipe is demonstrated in detail. The format is perfect for network engineers, explaining each problem and then diving deeply into the solutions.”
