=====Licensing=====

[[https://networklessons.com/cisco/ccna-routing-switching-icnd1-100-105/ios-licensing|NetworkLessons.com - IOS Licensing]]: 1900, 2900, and 3900 series routers use a universal IOS image that provide only the IP Base feature and require installation of a license key for features beyond IP Base. Routers before the mentioned series used an IOS image per features set, and to get a certain feature set you only needed the correct image to get that feature set. \\
[[https://learningnetwork.cisco.com/s/article/understating-cisco-ios-v15-licenses|The Cisco Learning Network - Understating Cisco IOS v15 Licenses]] (Yes, "understating". There are more spelling errors in the text of the article.) Mentions that IOS 15 is (only?) provided as a universal image. That would make IOS 15 require feature set licenses too?  \\
[[https://community.cisco.com/t5/switching/2811-router-ios-15-licensing/td-p/2079495|Cisco Community - 
2811 router IOS 15 licensing ?]] suggests that IOS 15 does not require license activation on a Cisco 2811 router, but it does on G2 routers like 2900, and 3900. \\
