For switches, this is what is included in the IP Base, IP Services, and Advanced IP Services
• IP Base is a baseline set of Layer 2 and Layer 3 Cisco IOS Software services required to operate Cisco Switches. IP Base includes all the features of LAN Base, plus Edge IP Routing (Static, RIP, & Basic PIM), HSRP/ VRRP, and GRE Tunneling. • Deployment Guidelines: LAN Wiring Closet
• IP Services is an advanced Cisco IOS Software feature set that supports full IP routing capabilities. IP Services includes all the features of IP Base plus full IP routing (EIGRP, OSPF & PIM), BGP, Policy Based Routing, GLBP, High Availability, Redundant PR+, Multi-VRF, WAN Protocols*, and enhanced QoS functionality (NBAR). Note Not all Switches support WAN Protocols and NBAR. • Deployment Guidelines: Advanced Wiring Closet, Switch Aggregation (Distribution and Core)
• Advanced IP Services is a comprehensive set of Cisco IOS Software features designed for IP-only networks. It includes all the features of IP Services plus additional features including IS-IS, MPLS, Layer 2 VPNs, Layer 3 VPNs. • Deployment Guidelines: Service Provider Environments, Enterprise: Campus WAN and Metro Edge
As for why the Advanced IP Services feature set was dropped after a certain IOS version, I don't know - perhaps someone else could answer that.
