CCIE Routing and Switching certification is for expert-level engineers who need to plan, operate and troubleshoot complex, converged network infrastructures. Before starting CCIE, training upto CCNP level should be completed then only you will be able to understand the technicalities.
Expertise in Routing and Switching is important as in any size of networking you will be working on routing and switching technologies for underlay connectivity.
All other technologies like Wireless, Data center, Security, Voice and many more are only usable if they have proper connectivity with required devices to build the network, that is the reason in each organization (who handle Networks) you will find at least one CCIE in Routing and Switching.
We can segregate the network in two terms: Enterprise and WAN(Internet). Setting up a network of an enterprise which mostly require understanding on technologies like: Vlan, VTP, STP, Etherchannel, Inter-vlan routing, IGP Routing and redistribution, Access-lists, different way for route filtering within the AS/Organization.
For WAN and Internet you should be expert in BGP, MPLS, VPN Technologies to connect the different sites of customer over the public cloud so that they can share the Intranet traffic. It also includes the RSVP, QOS and traffic engineering for the optimization of network.
In short after the completion if CCIE(R&S) one should be able to understand the design on large networks, implement and troubleshoot those networks.
