IS-IS is an interior gateway protocol that uses link-state routing and SPF algorithms to calculate the shortest path. It supports both CLNP and IP and has three routing levels - level 1 for intra-area routing, level 2 for inter-area routing, and level 1/2 routers that connect levels 1 and 2. There are three types of IS-IS routers: level 1 that exchange intra-area topology, level 2 that exchange inter-area topology, and level 1/2 that act as border routers between levels 1 and 2.
MPLS для чайников: основы технологии провайдеров и операторов связиSkillFactory
Вячеслав Васин – CCIE, инструктор Cisco, имеющий практический опыт реализации крупных MPLS-сетей – об особенностях технологии MPLS и о том, как эта технология используется в провайдерских сетях и операторах связи.
EVPN is a network virtualization technology that allows Ethernet services to be delivered across MPLS or IP networks. It uses BGP for the control plane to distribute MAC and IP addresses and can support both single-active and all-active multi-homing topologies. EVPN provides flexibility in service delivery and has been widely adopted by major service providers and cloud providers for a variety of use cases including data center interconnect and virtual machine mobility. Automation of EVPN configuration can simplify provisioning and management through the use of tools like NetBox, Python scripts, Ansible, and workflow managers.
This document provides an introduction to segment routing. It discusses:
- The objective of segment routing is to enable source routing without requiring state in intermediate nodes.
- Segment routing allows encoding paths as sequences of topological sub-paths called segments. Segments can represent nodes, links, or services.
- The IETF SPRING working group is standardizing segment routing to address issues with scalability of traffic engineering and fast reroute with protocols like RSVP-TE and LDP. Segment routing aims to provide these capabilities without per-flow state.

This document discusses segment routing and its benefits for incremental deployment in networks. It describes how segment routing uses MPLS or IPv6 routing headers to encode paths as ordered lists of segments. Segment routing allows more control over traffic paths compared to traditional IGP routing. It can enable traffic engineering and service chaining while maintaining network and control plane simplicity. The document argues segment routing is useful for scaling datacenters and simplifying peering relationships.
Designing Multi-tenant Data Centers Using EVPNAnas
This document describes the design of a multi-tenant data center network fabric using EVPN-IRB. It discusses the objectives of operational simplicity, workload placement flexibility, efficient bandwidth utilization, and multi-tenancy. It then describes the key components of the solution including BGP EVPN for control plane, overlay IRB for inter-subnet routing, distributed anycast gateways for workload mobility, and how the control and data planes interact for host learning and traffic forwarding.
This document provides an introduction and overview of MPLS (Multi-Protocol Label Switching). It defines MPLS, discusses why it was developed to address limitations in IP routing, and how it works by assigning labels to packets which are then forwarded based on the label rather than long IP address lookups. Key MPLS concepts covered include label edge routers, label switch routers, label switch paths, and protocols like LDP and RSVP-TE. Applications like traffic engineering and MPLS VPNs are also mentioned.
Segment Routing Advanced Use Cases - Cisco Live 2016 USAJose Liste
The document discusses segment routing and its use for inter-domain connectivity at scale. Segment routing allows source routing by encoding a path as an ordered list of segments in packet headers. It can be used to interconnect massive-scale datacenters and networks with hundreds of thousands of nodes. Segment routing scales through the use of globally unique prefix segments, redistribution of routing information only from the core to edges, and segment routing path computation elements. The path computation elements use segment routing native algorithms to optimize paths while maintaining equal-cost multipath routing.
The document provides information about a training event on Deploy MPLS Traffic Engineering taking place from 20 February to 2 March 2017 in Ho Chi Minh City, Vietnam. It includes details about two presenters - Nurul Islam Roman, Manager of Training & Technical Assistance at APNIC, and Jessica Wei, Training Officer at APNIC. It also acknowledges Cisco Systems and provides an agenda with topics on why MPLS Traffic Engineering is used and how it works.
Segment Routing is a source routing architecture that embeds instructions, called segments, directly in the packet. This allows packets to be steered through specific paths in the network by prepending or stitching segment IDs. Segment Routing simplifies network operations by removing the need for signaling, label distribution, and per-flow state. Paths can either be computed distributively using IGP flooding of segment IDs, or explicitly programmed by a controller. This provides flexibility to engineers while keeping the forwarding plane stateless and simple.
PLNOG 13: Emil Gągała: EVPN – rozwiązanie nie tylko dla Data CenterPROIDEA
Ethernet VPN (EVPN) is a new standards-based protocol that interconnects Layer 2 domains over a shared IP/MPLS network. It improves on previous protocols like VPLS by supporting features like all-active multi-homing and control plane learning of MAC addresses. EVPN is ideally suited for datacenter interconnectivity but can also be used in other cases beyond just data centers. Major networking vendors support EVPN as shown by their participation in the relevant IETF working group.

The document provides housekeeping notes for a Cisco Connect Toronto 2015 session. It reminds attendees to silence electronic devices, provides information on how to provide feedback and enter a prize drawing, and advertises the Cisco dCloud platform and Cisco Spark collaboration app. It also includes an agenda for the session on access network evolution, next generation EPN architecture, network services evolution, and SDN evolution.
The document summarizes the architecture of Juniper Networks routers. It discusses the separation of the control plane and forwarding plane. The control plane builds the routing tables while the forwarding plane is responsible for packet forwarding using specialized ASICs. It also describes the TX Matrix platform with up to 4 T640 routing nodes, each with 16 packet forwarding engines. The nodes are interconnected using a CLOS fabric switch.
This document provides an overview and agenda for a presentation on VXLAN BGP EVPN technology. It begins with an introduction to VXLAN and EVPN concepts. It then outlines the agenda which includes explaining VXLAN configuration, EVPN configuration, underlay configuration, overlay configuration, and EVPN VXLAN service configuration. It also provides a sample migration from a legacy device configuration to a VXLAN BGP EVPN configuration. Various networking acronyms related to VXLAN and EVPN are defined. Sample vendor supported data center technologies and a VXLAN test topology are shown.
Segment routing is a network technology focused on addressing the pain points of existing IP and Multiprotocol Label Switching (MPLS) networks in terms of simplicity, scale, and ease of operation. It’s a foundation for application engineered routing because it prepares the networks for new business models where applications can direct network behavior.
Segment routing seeks the right balance between distributed intelligence and centralized optimization and programming. It was built for the software-defined networking (SDN) era.
Segment routing enables enhanced packet forwarding behavior. It enables a network to transport unicast packets through a specific forwarding path, other than the normal shortest path that a packet usually takes. This capability benefits many use cases, and you can build those specific paths based on application requirements.
Segment routing uses the source routing paradigm. A node, usually a router but it can also be a switch, a trusted server, or a virtual forwarder running on a hypervisor, steers a packet through an ordered list of instructions, called segments. A segment can represent any instruction, topological or service-based. A segment can have a local semantic to a segment-routing node or global within a segment-routing network. Segment routing allows you to enforce a flow through any topological path and service chain while maintaining per-flow state only at the ingress node to the segment-routing network. To be aligned with modern IP networks, segment routing supports equal-cost multipath (ECMP) by design, and the forwarding within a segment-routing network uses all possible paths, when desired.
Design and Deployment of Enterprise Wirlesss NetworksCisco Mobility
This document discusses Cisco's controller-based wireless LAN architecture and mobility features. It covers:
1) The controller-based architecture uses wireless LAN controllers and access points to centralize management and control of wireless clients. Controllers handle client authentication, security, mobility, and network access across multiple access points.
2) Mobility is enabled through mobility groups, which allow controllers to peer with each other and exchange information to support seamless roaming across controller boundaries.
3) Cisco's technologies like CAPWAP, split MAC, and static IP mobility aim to make wireless roaming fast and seamless while maintaining security as clients move between access points and across subnets.
The document discusses the IS-IS routing protocol. It provides an overview of IS-IS, including that it is an interior gateway protocol used within an autonomous system. It also describes IS-IS levels, areas, and backbone routers. Finally, it discusses CLNS addressing, IS-IS PDUs like Hello packets, and other IS-IS concepts.
The document discusses key performance indicators (KPIs) for the E-UTRAN and EPC components of an LTE network, including accessibility, retainability, integrity, availability, and mobility metrics for E-UTRAN and accessibility, mobility, and utilization KPIs for EPC. It provides definitions and formulas for calculating various KPIs related to EPS attach success rate, dedicated bearer creation success rate, handover success rates, and other measures of network and service performance.
The document is a tutorial on L2VPN (Layer 2 Virtual Private Networks) that provides an agenda covering introductions, concepts, transports, services, pseudowire stitching, QoS, and demonstrations. It defines L2VPN as providing an end-to-end layer 2 connection across a service provider's MPLS or IP core, allowing legacy services like Frame Relay and ATM to be migrated to an MPLS/IP infrastructure. It also describes the need for L2VPN, models like VPLS and VPWS, basic building blocks of pseudowires, and control plane requirements.
