The "IP Services" feature set is the primary reason many network engineers choose this image. It transforms a Catalyst 3560 from a simple Layer 2 switch into a robust enterprise Layer 3 routing platform. The IP Services image includes dynamic routing protocols that are absent in the standard IP Base image, such as OSPF, EIGRP, and BGPv4. Additionally, it supports advanced features like and PIM (Protocol Independent Multicast) for IP multicast routing, making it suitable for use as a collapsed core or distribution-layer device in medium-sized enterprise networks. | | k9 | Indicates the image includes
