Cisco IOS packaging and feature licenses have changed quite a bit over the past several years. These changes span a variety of device platforms, so figured I’ll take two platforms/features that are commonly unknown and describe them briefly: one feature for the Catalyst 2K series switches and one licensing fact for the ISR G2 family of routers.
Inter-VLAN Routing with Catalyst 2960
A feature set of IOS came out that is called LAN BASE. Based on the particular switch platform, this could be and is usually Layer 2 only, i.e. 3K/4K/6K, and is aimed at being used in small to medium sized organization’s access layers. Cisco came out with this stripped down version of IOS with NO L3 (not even static routes) to compete with the HPs and DELLs of the world and has been pretty successful.
However, what is sometimes not known is Cisco introduced Layer 3 switching on the 2960S, 2960G, 2960, and 2975 series switches when running the LAN BASE IOS with version 12.2(55)SE. Pretty cool, right?
