Multi Home VxLAN-EVPN IRB with OSPF or ISIS

OcNOS DC : Virtual Extensible Local Area Network Guide : VxLAN - EVPN with Integrated Routing and Bridging Deployment Mode : Multi Home VxLAN-EVPN IRB with OSPF or ISIS

Overview

The support for Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (ISIS) protocols on Virtual Extensible LAN (VxLAN) Integrated Routing (IRB) interface is enhanced with multihoming switches that provides the solution for connecting and managing virtual networks within a data center or network infrastructure.

This feature offers flexibility in configuring network topologies, and ensures compatibility and interoperability within diverse network environments.

Note: Configure mutually exclusive secondary IP subnets between each anycast-IRB and CE within the same L2VNI in multi-homing scenarios or when the same IRB anycast interface is configured on multiple nodes. This ensures unique identification of the routing protocol peer.

Feature Characteristics

The OSPF and ISIS support over the IRB Interface with multihoming feature has the following characteristics:

• Connect the host node to two VTEPs with all-active redundancy mode. It helps forward all traffic from VTEP to the host when one VTEP goes down.

Benefits

The OSPF and ISIS support over the IRB Interface has the following benefits:

• Uninterrupted service between host and VTEP.

Prerequisites

• Router must be up and running.

• Maintain synchronization with VRF changes by performing IRB shut/no shut actions when specific events occur within the IPVRF. These events may involve adding or removing Route Targets (RTs), updating Route Distinguishers (RDs), or modifying Layer 3 Virtual Network Identifiers (L3VNIs).

Topology for OSPF

The network topology includes various network elements such as routers, customer edge (CE) devices, Service Aggregator (SA) devices, and Provider Edge (PE) routers. The feature enables OSPF on the IRB interfaces, allowing for efficient routing and communication between network devices within the topology.

Multi Home VxLAN	This refers to a Virtual Extensible LAN (VxLAN) deployment where a Multi data center or network site is connected to a Multi external network (usually the internet) for connectivity.
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.
