Lectures:
- Practical reasons for the division of L2 and L3. Scalability of switched and routed networks, connection of addressing with the physical location of endpoints. Switching at OSI layer 3 RM. Multilayer switching. Routing between VLANs. L2 security.
- Link aggregation. Use of VLANs in enterprise networks and in DCi environment.
- Redundancy in switched networks: advanced variants of Spanning Tree (STP), STP protection. STP replacement options – routed VxLANs.
- Routing, reminder of the basics of routing including the default path. Classification of routing protocols. Distance Vector routing protocols – concept, advanced features, use.
- Link State routing protocols. Advanced OSPF topics: principle, areas, topological database, building a routing table. Function on various network types, multi-area OSPF, IS-IS.
- IPv6 specifics and routing in IPv6. OSPFv3, MP-BGP. Parallel IPv4 and IPv6 routing.

- Route optimization between autonomous systems, BGP attributes and policies. BGP in deployments outside ISP networks. Using BGP to protect against DDoS attacks.
- Multimedia application support: Multicast, L2 and L3 multicast addresse. IGMP and MLD. Multicast routing: reverse-path forwarding, distribution trees. PIM protocol and its modes, MSDP.
- Design of reliable IP networks.
- QoS support in networks: Integrated Services and Differentiated Services. RSVP, L2 and L3 traffic classification and prioritization, IEEE 802.1p, NBAR. Queuing strategies. Traffic shaping and limiting.
