60. Traditional Networking Methodology 60 • Logging in manually with a password • Typing commands • Copy and paste over console or terminal • Checking box by box
61. 61 Step 1: Using Git & GitHub § Configuration file repository § File change and revision management § Build for teams to work the same files
62. 62 Step 2: Commit Your Configuration $ git add . $ git commit -a -m "Add new switch configuration" –s [master 8cf8a38] Add new switch configuration 1 file changed, 1 insertion(+) create mode 100644 ofswitch.conf $ git push -u origin master

65. 65 Ansible Network Modules Ref: http://docs.ansible.com/ansible/list_of_network_modules.html
66. 66 Step 4: Templatize Configuration Files • Let you reuse code snippets • Avoid human error and typos
67. 67 Step 5: Virtualize Copy of Network
68. 68 Step 6: Continuous Integrations System • Catch error or typos early • Make sure all of the setting is same as production

73. 1 FRR - A new Quagga fork with a more open development Martin Winter mwinter@opensourcerouting.org 73 Ref: https://frrouting.org/
74. What is FRR ? ‣ Open Source (GPLv2+) Routing Stack ‣ Implements RIP, RIPng, OSPF (v2&v3), ISIS, BGP, PIM, LDP ‣ Fork of Quagga ‣ Works on Linux and most BSD based systems ‣ For use in many Clouds as virtual routers, white box vendors and network providers (full routing stack) 2 (for the not so technical People) 74
75. FRR - Why a new fork? 3 Open Development Model Faster Development Community Driven 75
77. FRR - What’s different? ‣ Methodical vetting of submissions ‣ More automated testing of contributions ‣ Github centered development ‣ Elected Maintainers & Steering Committee ‣ Common Assets held in trust by Linux Foundation 5 77
78. FRR – Current Status 78 Ref: https://github.com/FRRouting/frr/wiki/FRR-2.0-%E2%86%92-FRR-3.0
79. • Open Networking 是趨勢，並正在發生 • Open Source + Commercial • 跨領域整合需求大幅增加，但只賣單一領域的產品 • Total Solution / Turnkey Solution • 自己掌握自己命運 • 網路工程師能力呈現 M 型化 • Coding 是必備技能 • 與 Community 協作能力越來越重要 • 跨領域能力要求更多 Conclusion 79
