Service providers, more than ever, are looking for ways to reduce network operational costs while increasing new revenue streams through over-the top services. ExtremeRouting CER 2000 Series Routers are purpose-built to help these providers save on space, power, and cooling while extending wire-speed IP and Multi-Protocol Label Switching (MPLS) services to the network edge without compromising performance.

The CER 2000 is available in 24-port 1 Gigabit Ethernet (GbE) copper and hybrid fiber configurations with four 10 GbE uplink ports. To help ensure high performance, all the ports are capable of forwarding IP and MPLS packets at wire speed without oversubscription.

A broad set of highly scalable IP unicast and multicast routing features, combined with a low total cost of ownership, makes the CER an ideal choice for service providers that want to deliver Layer 2 and Layer 3 business services through a single, easy-to-manage platform.

Scalable Carrier-Class Routing

The CER 2000 features best-in-class interior and exterior gateway protocols that are commonly deployed in provider networks. The routers support standard IPv4 and IPv6 routing protocols-including Routing Information Protocol (RIP/RIPng), Open Shortest Path First (OSPF/OSPFv3), Intermediate System-to-Intermediate System (IS-IS/IS-IS for IPv6), and Border Gateway Protocol (BGP/BGP-MP for IPv6)-with the same performance and reliability typically associated with larger chassis systems. To complement these routing features, the CER can store the full Internet routing table in hardware and achieve wire-speed forwarding performance. As a result, it is ideally suited for service provider edge routing applications as well as for enterprise border routing applications.


  • Compact 1U, IP/MPLS, NEBS Level 3-certified router, purpose-built for high-performance Ethernet edge routing applications
  • Scalable edge router designed to support a full Internet routing table along with MPLS forwarding for advanced business and residential services, service provider data center interconnect, and Internet peering
  • Available in 24-port 1 GbE plus 4-port 10 GbE versions for both copper and fiber with non-blocking wirespeed performance and a complete suite of IPv4/IPv6 unicast and multicast routing supporting fast convergence times
  • Powered by the field-proven ExtremeRouting Multi-Service IronWare OS that also runs on the ExtremeRouting MLXe Series of highperformance core routers
  • Advanced QoS features to enforce strict SLAs at the edge of the network

Key Applications

  • Edge routing applications in Metro Ethernet networks
  • MPLS-based Layer 2 and Layer 3 VPN services
  • Provider edge routing for triple-play/ IPTV delivery
  • Provider-managed router in end-user customer premises
  • Compact BGP route reflector
  • Data center or campus border routing
  • Virtualized data center or campus applications with multi-VRF

Compact and Scalable Routing

The CER can store up to 1,500,000 IPv4 and 256,000 IPv6 unicast routes, enough to accommodate the full IPv4 Internet routing table today and provide a smooth migration path to IPv6. In addition, the ExtremeRouting Neltron operating system provides highly scalable BGP functionality and can support up to 256 BGP peers. Combined with advanced and scalable BGP route filtering mechanisms, the CER can be a route reflector in small to midsized networks.

Video Delivery

As more and more service providers include digital entertainment (using MPEG2/4-quality video) in their offerings, they require enormous amounts of bandwidth per subscriber and efficient multicast delivery. Providing up to 136 Gbps of capacity, the CER is ideally suited for the high-bandwidth, low-latency requirements of video traffic. Today, service providers deliver triple-play and IPTV services using both Layer 2 and Layer 3 models.The CER gives them the flexibility of choosing between traditional IP multicast and Virtual Private LAN Services (VPLS) to deliver high-quality video.

The CER provides comprehensive support for multicast routing and switching through a variety of protocols- including PIM-SM, PIM-DM, PIM-SSM, IGMP v2/v3-and through other platform-independent capabilities. Egress interface-based replication optimizes performance and buffer usage to help maximize network performance for multicast traffic. In addition, the CER supports static IGMP “Joins” and efficient processing of IGMP Join/Leave requests to help ensure a fast channel-zapping experience.

Carrier-Class Reliability
Routing stability and non-stop forwarding are key attributes in maintaining high Service Level Agreements (SLAs) in provider networks. To facilitate higher SLAs, the CER supports graceful restart helper mode for both OSPF and BGP. In addition, it supports Bidirectional Forwarding Detection (BFD) for OSPF, IS-IS, and BGP, streamlining the detection of network failures and enabling sub-second convergence. The CER supports up to 8 Equal-Cost Multi-Paths (ECMPs), which can help increase redundancy. Moreover, redundant, load-sharing power supplies help ensure complete carrier-class uptime.

MPLS to the Edge
Triple-play services and business Virtual Private Network (VPN) solutions are increasingly based on MPLS infrastructure. Given the enormous space constraints and the need to deliver Layer 2 and Layer 3 services in a single device, many service providers are looking for a device that can deliver maximum performance in the smallest footprint. The Extreme CER meets this objective with advanced MPLS edge features-making it an ideal platform for delivering converged voice, video, and data over MPLS in small to midsized Metro Ethernet networks.

Business VPNs

With the CER Series, service providers can offer distributed enterprise connectivity services through a transparent service such as Layer 2 VPNs, or provide more control through Layer 3 VPN services. The transparent services are delivered as point-to-point or point-to-multipoint services. To facilitate both options, the Extreme CER Series supports VPLS and Virtual Leased Line (VLL) implementations using widely accepted LDP signaling. The routers also support Border Gateway Protocol (BGP)-based MPLS VPNs and provide per-customer routing instances with a choice of BGP, Open Shortest Path First (OSPF), Routing Information Protocol (RIP), or static routing options. In addition, each virtual forwarding interface supports inbound and outbound Access Control Lists (ACLs) and rate-limiting features for accounting and Service Level Agreement (SLA) enforcement. Figure 1 shows how the Extreme CER , in conjunction with the ExtremeRouting MLX® Series, provides a scalable Layer 2 and Layer 3 VPN solution.

Service Management

Delivering effective MPLS services on Carrier Ethernet infrastructure requires fast fault identification and isolation. The CER supports MPLS Labeled Switch Path (LSP) pings and traceroute features to isolate any MPLS-related connectivity issues. In addition, it supports all the capabilities of IEEE 802.1ag (Connectivity Fault Management), including Connectivity Check Messages, Loopback Message/Response, and LinkTrace Message/ Response. IEEE 802.1ag, in conjunction with the MPLS OAM features, provides the capabilities to monitor, isolate, and identify connectivity problems and reduce the time to repair business VPN services. To diagnose link layer connectivity issues, the CER also supports the IEEE 802.3ah Link OAM feature. In addition, the CER is certified to comply with MEF 17 Service OAM and MEF 21 Link OAM specifications.

Delivering High Service Levels with Advanced QoS Capabilities

Service provider business services are often tiered under different service levels, ranging from premium to “besteffort” services. At each level of service, providers must meet or exceed customer agreements-and failing to do so can lead to strict financial penalties and loss of business. As a result, Quality of Service (QoS) is a critical factor in creating selective services and meeting SLAs.

The CER 2000 supports up to eight queues per port, each with a distinct priority level-enabling service providers to sell multi-tiered business VPN services. By applying advanced QoS capabilities (such as the use of two-rate, three-color traffic policers, egress shaping, and priority remarking), service providers can offer guaranteed service levels to customers. In addition, the CER supports ingress and egress bandwidth profiles per User Network Interface (UNI) that comply with the rigid traffic management specifications of MEF 10/MEF 14.

Virtualized Domains with Multi-VRF

Just as VLANs segment a Layer 2 domain into multiple broadcast domains, Multi-Virtual Routing and Forwarding (Multi-VRF) enables a single Layer 3 domain to be segmented into multiple virtual IP domains. This enables enterprise or service provider networks to support two or more VPNs with overlapping IP address spaces on the same router or physical interface-rather than deploying multiple physical routers. Each VPN can be dedicated to traffic from a specific application or from a specific group of users for greater security and manageability.

The CER 2000 supports up to 128 VRFs and can hold a full Internet routing table inside a VRF. It also has the capability to dynamically exchange routing information within each VRF using multiple routing protocols, such as BGP, OSPF, or RIP. In addition, the CER enables route exchanges between VRFs, which helps service providers or large enterprises use a single VRF as a gateway to the Internet while running confidential mission-critical traffic in other VRFs.

Enforcing Security at the Edge

Edge routers are usually the first line of defense for service providers, either protecting their own cores or their business customers from Denial of Service (DoS) attacks. The CER 2000 has a comprehensive set of hardware-based security features to monitor and block unwanted traffic.

Both inbound and outbound Access Control Lists (ACLs) are supported on any kind of interface-physical, trunk groups, or virtual interfaces. In addition, the CER supports sFlow- and ACL-based mirroring to help monitor malicious traffic and take preventive actions. To increase the reliability of service delivery, the CER (with the help of Receive ACLs) can defend itself against unwanted traffic targeted toward its control plane.

Software-Defined Networking

Software-Defined Networking (SDN) is a powerful network paradigm that provides increased agility and deterministic control of network infrastructure, enabling a new class of IT applications to meet critical business needs. Such applications may include improved traffic management, network utilization and security. The CER 2000 enables SDN via OpenFlow 1.3 support and scales to support up to 32,000 flows in a single device. The CER 2000 delivers OpenFlow in hybrid switch mode, meaning the CER can be configured to simultaneously forward traffic via traditional Layer 2 switching and Layer 3 routing along with OpenFlow-based forwarding on the same device.

This highly differentiated approach enables organizations to seamlessly integrate SDN into existing networks, giving them the agility and fine-grained deterministic control offered by SDN for specific traffic flows, while the remaining traffic is handled via traditional switching and routing. OpenFlow 1.3 delivers a feature set required for commercial and enterprise networks to address complex network behavior and optimize performance for dynamic applications. These features include Quality of Service (QoS), Q-in-Q, Group Tables, Active-Standby Controller, and IPv6.

Simplified Service Management

To simplify the manageability and provisioning of Ethernet services, the CER 2000 Series leverages Network Advisor, an application that unifies network management for all products. Network Advisor provides the easy-to-use MPLS Manager, which can help configure, monitor, and manage VPLS and Virtual Leased Line (VLL) services across networks that are based on routers. In addition, the sFlowbased technology utilized by Network Advisor reduces network downtime with proactive monitoring, traffic analysis, and reporting.
