Smart Router supports Virtual Private Wire Service (VPWS), a point-to-point service where the attachment circuit from the CE device is connected to a pseudowire at PE The pseudowire carries a layer packet over the MPLS and/or IP backbones to the remote PE where it is connected to the remote CE device via an attachment circuit Multi-segment functionality can be used with other pseudowire types as well More information on the Ethernet functionality can be found in the 8600 Smart Routers Ethernet Configuration Guide F03530 Ethernet Raw Mode PWE F03528 Ethernet Tagged Mode PWE F03529 Dynamic

pseudowire redundancy is not supported for QinQ attachment circuits 3.6.6 Ethernet OAM Ethernet Operation, Administration and Maintenance (OAM) is a set of functions designed to monitor network operation in order to detect network faults and measure its performance Ethernet OAM is not supported in the initial release 3.6.7 Integrated Routing and Bridging In Integrated Routing and Bridging (IRB) a logical Ethernet switch is placed before the IP routing function In this way multiple physical Ethernet ports may be connected to a logical IP interface The function is needed e.g in RNC protection cases, because the RNC protection model is often designed as assuming an Ethernet switch layer between the RNC and the router By using IRB there would be no need for external Ethernet switches IP routing functions in the normal way, except for the fact that the IP interface is attached to the Ethernet switch instance instead of a physical port A more likely application for IRB in the 8665 Smart Router is to allow Layer solution in access network and move to Layer in aggregation network F03563 Integrated Routing and Bridging 8600 Smart Routers SR7.0 Product Definition 22 76.8670-40125A © 2015 Coriant 8665 Smart Router Limitations and Restrictions in IRB • IRB cannot be used with LAG interface • IRB functionality requires two lookups and thus there will be some impact to forwarding performance • MPLS over IRB is not supported • ECMP over IRB is not supported 3.7 IPv4 Routing The 8665 Smart Router supports OSPFv2, IS-IS and BGP-4 routing protocols OSPFv2 and IS-IS IGP protocols support traffic management extensions as well The 8665 Smart Router supports [RFC4364] Layer VPN, which requires MP-BGP protocol support Inter AS options A, D and C are supported Inter AS option D is interoperable with the more common Inter AS option B The main difference between these options is that Option D performs IP lookup, which allows route aggregation at ASBR The 8665 Smart Router supports protocol authentication for OSPF, IS-IS, BGP and LDP Bidirectional Forwarding Detection can be used with BGP, OSPF and IS-IS routing protocols for fast default detection Packet Loop Test can be used to verify IP service performance The 8665 Smart Router runs the same 8600 operating system as the other 8600 Smart Routers See the 8600 Smart Routers Routing Protocols Configuration

Ping and Traceroute F03616 Packet loop test 3.8 MPLS Switching and Signaling The 8665 Smart Router supports multiprotocol label switching and can function in both Label Switching Router (LSR) and Label Edge Router (LER) position In MPLS forwarding the forwarding decision is done based on the label value located in the shim header of an MPLS packet The forwarding information is contained in the Incoming Label Map (ILM) and Forwarding Equivalence Class To Next Hop Label Forwarding tables (FTN) The information in the ILM and FTN can be configured either statically by management command or dynamically using a label distribution protocol The 8665 Smart Router supports the following mechanisms to assign and advertise MPLS labels: • LDP for outer label (LSP) distribution • Targeted LDP for inner label (pseudowire and VPLS label) distribution • RSVP-TE for outer label (LSP) distribution • MP-BGP for inner label (IP VPN) distribution • BGP Labeled Unicast is supported for Seamless MPLS

Coriant 8665 Smart Router 3.9 Traffic Management The 8665 Smart Router has similar traffic management functions as the ELC1 card in the 8660 Smart Router The Traffic Classification, Policing, Queue Management, Scheduling and Shaping functionality within the 8600 network elements are fully based on the Differentiated Services (DiffServ) architecture and protocol standards of the Internet Engineering Task Force (IETF) The 8665 Smart Router supports seven IETF-standardized PHB Scheduling Classes (PSCs): CS7, EF, AF1 and BE Tail drop queue management is used for CS7 and EF classes, WRED/RED for AF1 and BE classes VLAN and port shaping is supported in hierarchical manner at egress VLAN shaping is applied to a group of queues associated with a single or multiple VLANs The 8665 Smart Router can classify packets based on DSCP field, Multiprotocol Label Switching (MPLS) EXP bits (Renamed to Traffic Class field [RFC5462]), and Ethernet VLAN User Priority bits In addition to this, ACLs are used for implementing the DiffServ Multi-Field (MF) classifiers For L2 services like Ethernet Pseudowires, the traffic classification can be performed based on Ethernet PRI bits DSCP classification is not supported for L2 services The 8665 Smart Router supports ingress policing with a two-rate Three-Color Marker (tr-TCM) [RFC2698] For more information on traffic management, refer

balanced IF F03587 SCI/SCO unbalanced 75ohm F03613 Network Timing Protocol (NTP) 3.11 Security The 8665 Smart Router supports Access Control Lists, which can be used to specify network traffic Once you specify traffic with an ACL, you can a variety of things with it For example, you can permit, deny, or reject traffic The 8665 Smart Router can protect the host processor against DoS attacks by limiting the number of packets forwarded to processing The following actions are supported: • Permit • Deny • Reject (deny and ICMP notification to sender) • QoS change • Policy based routing More information about ACL functionality can be found in 8600 Smart Routers IP Forwarding and Traffic Management Configuration Guide For the security features supported by routing and signaling protocols,

inherits most of its features from the ELC1 implementation However, some features are not supported by 8665 Smart Router in FP7.0 but will be considered in later releases: • MPLS-TP • ECMP • RSVP-TE tunnel source statistics • 100M optical SFP support • 10/100M electrical SFP support • SyncE capable electrical 100/1000Base-TX SFP support • Interface hold down timer • IEEE1588 L2 Boundary Clock • IEEE1588 L2 Master • IEEE1588 L2 Slave Ethernet OAM 76.8670-40125A â 2015 Coriant 8600 Smart Routers SR7.0 Product Definition 27 8615 Smart Router 8615 Smart Router 4.1 F00539 – Stacking of Two 8615 Smart Router NEs This feature allows the 8615 Smart Router to be used as aggregation router where more capacity and protection capabilities are needed Stacking of two elements will meet those requirements and thus the 8615 can provide a viable alternative to bigger and often more expensive routers Half-meter and two-meter-long stacking cables are available The 8615 Smart Router HW has a connector that can be used for stacking two devices together using a dedicated interface and a cable This interconnects the forwarding NPUs of the two elements using internal direct link, providing up to 44 Gbps throughput This creates a redundant hardware with double capacity Control plane is protected, since in case of failure the control plane is switched to working unit Forwarding plane protection is implemented using available traffic protection mechanisms, like ELP or RSVP-TE 1:1 In case of ELP, the members of the protection group must reside in different units From network management perspective the 8615 Smart Router stacked is seen as one network element In 8615 stacked configuration the virtual CU process runs on both 8615 units If the 8615 unit having the active CU role fails, the 8615 performs two actions simultaneously: • Traffic re-routing for traffic destined to ports in the failed 8615 unit • Performing CU switchover to another 8615 unit The CU switchover can delay rerouting of the traffic There are three types of traffic impacts: • No impact to traffic not destined to failed unit • Any hard-real-time (BGP MP, ELP, ECMP, some cases of RSVP 1:1) protected traffic destined to failed unit experience normal protections switch with same performance as with regular line card failure (e.g
