Glossary
The following provides definitions for key terms used throughout this document.
Single Home EVPN-MPLS | A network architecture that combines EVPN and MPLS to provide efficient and scalable Layer 2 and Layer 3 services within a network, particularly in SP environments. |
IRB | A networking feature that enables the integration of Layer 3 IP routing and Layer 2 MAC address bridging within the same interface, simplifying network management and resource utilization. |
OSPF | A dynamic and efficient link-state routing protocol used to determine the best path for data packets in an IP network. It is characterized by rapid convergence and adaptability, making it suitable for large and dynamic networks. |
ISIS | A routing protocol designed for scalability and stability in computer networks, commonly used in large Service Provider networks. It provides a robust framework for routing information exchange. |
Layer 3 Routing | Network routing operations at the Network Layer (Layer 3) of the OSI model, focusing on routing IP packets between different subnets or networks. |
Layer 2 Bridging | Network bridging operations at the Data Link Layer (Layer 2) of the OSI model, handling the forwarding of data frames based on MAC addresses within the same network segment. |
EVPN | Ethernet VPN, a technology that provides advanced and efficient methods for Layer 2 and Layer 3 services in Ethernet networks, often used in data centers and service provider environments. |
