Nokia 7250 IXR-e Interconnect Routers - Al-enterprise

Nokia 7250 IXR-e Interconnect RoutersRelease 20Routers in the Nokia 7250 Interconnect Router (IXR)-e series1 are usedfor access and aggregation and as 5G multi-access edge computing(MEC) leaf nodes. They are ideal for IP anyhaul and fixed-mobileconvergence.Ready for growthThe 7250 IXR-e series features high systemthroughput and a variety of interfaces. 100GEports used for high-speed uplinks enable costeffective 100GE ring architectures.5G mobile and telco cloud infrastructures aremoving toward 25GE interfaces. On the 7250IXR-e series, the native 25GE ports are capableof supporting 1GE,2 10GE or 25GE transceivers.Combined with support for GE SFPs in all SFP cages, the 7250 IXR-e allows for seamlessmigrations from 1GE to 10GE to 25GE rateswithout the need to replace the router.7250 IXR-e 2QSFP28 8SFP28 24SFP 7250 IXR-e 14SFP 4RJ45Compact and powersavingDifferentiated servicesupportThe 7250 IXR-e’s compact (1RU) size and extendedtemperature range make it ideal for outside cabinetapplications. It is ETSI 300-mm compliant, withall-up-front access and side-to- side air flow.A fan filter and redundant fans increase systemlifetime and reduce maintenance costs.The 7250 IXR-e series supports low-latencyapplications while providing a large buffer memoryfor delay-tolerant applications. Very granularper-service and per-forwarding class policingand queuing features support differentiatedquality of service (QoS), making the 7250 IXR-eseries ideal for any-G aggregation and fixedmobile network convergence.7250 IXR-e systems consume approximately15 percent less power than equivalent competingsystems. Mass deployments for 5G will benefitsignificantly from this green design.121The 7250 IXR-e series is part of the 7250 IXR product family.

AutomationThe 7250 IXR-e series uses the Nokia ServiceRouter Operating System (SR OS) and is managedby the Nokia Network Services Platform (NSP), whichoffers a rich set of service management featuresthat automate end-to-end service provisioningand operations, administration and maintenance(OAM) to enhance end-user experience and reduceoperating costs.Standards-based software-defined networking(SDN) interfaces enable best-path computation tobe offloaded to path computation elements (PCEs)such as the Nokia NSP. 7250 IXR-e-series routersoperating as path computation clients (PCCs) collectand report per-link and per-service delay, jitter andloss metrics together with port utilization levels,for efficient path computation.Software featuresThe 7250 IXR-e series supports, but is not limitedto, the following features.Services Point-to-point Ethernet pseudowires/virtualleased line (VLL) Ethernet Virtual Private Network (EVPN)– Virtual Private Wire Service (EVPN-VPWS)– Virtual Private LAN Services (EVPN-VPLS):IPv4 and IPv6 support, including VirtualRouter Redundancy Protocol (VRRP)– Multihoming with single active or active/activeNetwork protocols Segment routing– Intermediate System-to-Intermediate System(SR-ISIS) and Open Shortest Path First (SR-OSPF)– Traffic engineering (SR-TE) IPv4, IPv6 MPLS label edge router (LER) and label switchingrouter (LSR) functions– LDP– Resource Reservation Protocol with trafficengineering (RSVP-TE) BGP Labeled Unicast (LU) (RFC 3107) route tunnels IP routing– Dual-stack Interior Gateway Protocols (IGP)– Multi-topology, multi-instance IS-IS– Multi-instance OSPF– Multiprotocol BGP (MP-BGP)– BGP-LU support in edge, area border router(ABR) and autonomous system boundaryrouter (ASBR) roles– Usage-triggered download of BGP label routesto Label - Forwarding Information Base (L-FIB)– Accumulated IGP (AIGP) metric for BGP– BGP monitoring protocol (BMP)– BGP route-reflector for EVPN and IP-VPN withVPNv4 and VPNv6 address families (AFs)– BGP confederations Layer 3 Multicast - base routing Multipoint Ethernet VPN services with VPLS basedon Targeted Label Distribution Protocol (T-LDP)and Border Gateway Protocol (BGP)– Internet Group Management Protocol (IGMP) Routed VPLS with Internet Enhances Services(IES)/IP-VPN IPv4 and IPv6– Multicast Listener Discovery (MLD) Ingress and egress VLAN manipulationfor L2 services IP VPN (VPRN), Inter-Autonomous System(Inter-AS) Option A, B, and C IPv6 VPN Provider Edge (6VPE)– Protocol Independent Multicast – Sparse Mode(PIM-SM), Source Specific Multicast (SSM) Layer 3 Multicast - VPRN– Next-generation multicast VPNs (NG-MVPN)– SSM with multicast LDPv4 (mLDPv4)– IGMP/MLD– IGMP/MLD on Routed VPLS Interface Layer 2 Multicast– IGMP/MLD snooping2Data sheetNokia 7250 IXR-e Interconnect Routers
