to answer your question, the Cisco Collaboration, Cisco Routing and Switching with Firewall Clusters, and Cisco Service Provider (CE) technologies can actually exist both separately and together, you have to look on the network design and business requirements. Cisco Collaboration focuses on voice, video, and unified communications and typically relies on a stable underlying infrastructure provided by routing, switching, and firewall systems. Routing and Switching with Firewall Clusters form the core network foundation, enabling connectivity, segmentation, and security for all services, including collaboration and external connections. Cisco Service Provider (CE), commonly used in ISP or MPLS networks, connects customer networks to provider networks and often integrates with routing and firewall components in enterprise environments.
