This release introduces support for enhanced Ethernet capabilities, advanced Layer 3 routing, and Multiprotocol Label Switching (MPLS) support.
This product bulletin contains content and delivery information for Cisco IOS Software Release 12.2(52)EY.
Table 1 shows the new features in Cisco IOS Software Release 12.2(52)EY.
Table 1. New Features
Flexible Ethernet Services
• Ethernet virtual connections (EVCs): Ethernet services are supported using individual EVCs to carry traffic belonging to a specific service type or end user through the network.
• Flexible VLAN classification: VLAN classification into Ethernet flow points (EFPs) includes single-tagged VLANs, double-tagged VLANs (QinQ), contiguous VLAN ranges, and noncontiguous VLAN lists.
• Flexible VLAN tag manipulation: VLAN manipulation includes explicit pop functions (1 or 2) and implicit push (1). QinQ and selective QinQ are also supported.
• IEEE bridging: The software supports native bridging based on IEEE 802.1Q and QinQ VLAN encapsulation mechanisms.
• Virtual Private WAN Services/Ethernet over MPLS (VPWS/EoMPLS): EoMPLS transports Ethernet frames across an MPLS core using pseudowires. Individual Ethernet flow points, VLANs, or an entire port can be transported over the MPLS backbone using pseudowires.
• Pseudowire redundancy: Pseudowire redundancy supports the definition of a backup pseudowire to protect a primary pseudowire that fails.
• Per VLAN MAC learning: PVL allows control of MAC learning on a per-VLAN basis and deactivation of learning on a per-L2VPN-services basis.
• EVC MAC limiting: To limit MAC address entries per Ethernet flow point.
Layer 3 Routing and VPN Services
• IPv4 routing:Support for Border Gateway Protocol (BGP), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol (RIP v1 and v2), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), static routing, Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol (VRRP) features.
• MPLS L3VPN:The IP VPN feature for MPLS allows deploying scalable IPv4 Layer 3 VPN backbone services.
• Multi VRF CE (VRF Lite):Multi VRF CE allows you to extend the VRF concept to the customer edge (CE) device using VLANs to carry VPN information to the provider edge (PE).
• MPLS and MPLS TE:Support for MPLS protocols such as Traffic Engineering/Fast Reroute (TE-FRR), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), and Targeted Label Distribution Protocol (T-LDP).
• IPv4 Multicast: IPv4 Multicast supports Internet Group Management Protocol Versions 2 and 3 (IGMPv2/v3), Protocol Independent Multicast (PIM) Source-Specific Multicast (SSM), Sparse Mode (SM), Dense Mode (DM), and Spare Dense Mode (SDM) PIM SSM mapping.
• IGMP v1/v2/v3 snooping: This Layer 2 mechanism efficiently tracks multicast membership on an L2VPN network. Individual IGMP joins are snooped at the VLAN level, and then results are summarized into a single upstream join message. With IGMP v3 snooping, join and leave requests are processed as v2 joins and leaves.
• QoS: Comprehensive quality-of-service (QoS) support with support for thousands of queues and hierarchical QoS with ingress policing, marking, and egress shaping.
• Ingress QoS: Advanced ingress classification including Layer 2 and Layer QoS access control list (ACL), classification based on inner and outer class of service (CoS), or VLAN ID. Ingress policing with 2-rate 3-color (2R3C) policers for enhanced L2VPN definition. Ingress marking including outer CoS, DSCP, MPLS exp bits, and QoS group.
• Egress QoS with 3-level hierarchy (H-QoS) with egress shaping per port and per queue, class-based weighted fair queuing (CBWFQ), and priority queuing.
• Cisco modular QoS CLI (MQC). Modular CLI is used to configure various QoS features on various Cisco platforms.
• E-OAM (IEEE 802.1ag): Ethernet Connectivity Fault Management is a subset of Ethernet Operations, Administration, and Maintenance (EOAM) protocol that provides numerous mechanisms and procedures for the discovery and verification of the path through 802.1 bridges and LANs.
• E-OAM (IEEE 802.3ah): Ethernet link layer OAM provides a physical-link OAM to monitor link health and assist in fault isolation.
• MPLS OAM: This protocol supports label-switched-path (LSP) ping, LSP TraceRoute, and virtual circuit connectivity verification (VCCV).
• Ethernet E-LMI: Support for E_LMI CE and PE for exchange of an EVC state and attributes between the provider edge (PE) and customer edge (CE). E-LMI interaction with CFM (IEEE 802.1ag) extends the status of the EVC and remote UNI to the CE device.
• IEEE 802.1s Multiple Spanning Tree (MST): MST extends the 802.1w Rapid Spanning Tree Protocol (MSTP) to multiple spanning trees, providing rapid convergence and load balancing.
• Cisco Resilient Ethernet Protocol (REP): REP provides fast convergence for Layer 2 deployment in ring topologies. REP support in this release includes REP Edge No Neighbor feature to interact with non-REP devices.
• Flexlink for dual homing: Used in hub-and-spoke topology with dual homing, Flexlink provides fast convergence in Layer 2 topologies. Flexlink supports active-active links with VLAN load balancing.
• MPLS TE FRR: MPLS Traffic Engineering (TE) Fast Reroute (FRR) delivers Layer 3 protection switching for networks currently configured with MPLS LSPs. MPLS TE FRR provides temporary rerouting around a failed link or node.
• Bidirectional Forwarding Detection (BFD): BFD is a detection protocol that is designed to provide fast-forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols.
• Standard IEEE 802.3ad link aggregation bundles: A bundle of multiple links can be supported to provide added resiliency and the ability to load balance traffic over multiple member links.
• Cisco Active Network Abstraction (ANA): Cisco ANA is a flexible, vendor-neutral network resource-management solution for a multitechnology, multiservice network environment.
• CiscoWorks LAN Management Solution:CiscoWorks LAN Management Solution 3.2 is an integrated suite of management functions that simplifies the configuration, administration, monitoring, and troubleshooting of an end-to-end borderless network.
• Layer 2 ACLs: You can use this security feature to filter packets.
• Layer 3 ACLs: This feature matches ACLs by IPv4 protocol packet attributes.
