IPv4

Supports the static routing protocol and dynamic routing protocols, such as RIP, OSPF, IS-IS, and BGP-4. All ports support line-rate forwarding even in complex routing environments, for example, when route flapping occurs

IPv6

Supports the following:

• IPv4/IPv6 dual stacks

• A variety of IPv4-to-IPv6 transition technologies: Manually configured tunnels, IPv6 over IPv4 tunnels, GRE tunnels, IPv4 over IPv6 tunnels, and IPv6 Provider Edge (6PE)

• IPv6 static routes and dynamic routing protocols, such as BGP4/BGP4+, RIPng, OSPFv3, and IS-ISv6

• IPv6 neighbor discovery, PMTU discovery, TCP6, ping IPv6, tracert IPv6, socket IPv6, static IPv6 DNS, IPv6 DNS server, TFTP IPv6 client, and IPv6 policy-based routing

• Network Address Translation IPv6-to-IPv4 (NAT64), NAT44 and Dual-Stack Lite (DS-Lite)

Internet Control Message Protocol Version 6 (ICMPv6) Management Information Base (MIB), User Datagram Protocol Version 6 (UDP6) MIB, TCP6 MIB, and IPv6 MIB

MPLS/MPLS VPN

Supports the following:

• MPLS TE and MPLS/BGP VPN in compliance with RFC 2547bis

• Inter-AS Option A, inter-AS Option B, and inter-AS Option C

• Integration with Internet services

• Martini MPLS L2VPN and Kompella MPLS L2VPN

• VPLS and VLL

• Heterogeneous interworking

Multicast VPN

Layer 2 Features

Supports the following:

• Protocols such as IEEE 802.1Q, IEEE 802.1ad, IEEE 802.1D, IEEE 802.1w, and IEEE 802.1s

• VLAN aggregation (super VLAN)

Filtering list based on MAC addresses and ports

Reliability

Supports the following:

• Protection mechanisms such as IP/LDP/VPN/TE/VLL FRR, IP/TE automatic rerouting, fast convergence of IGP/BGP/multicast routes, VRRP, load balancing among IP-Trunk links, BFD, MPLS/Ethernet OAM, and routing protocol/port/VLAN damping

• PW redundancy, E-Trunk, E-APS, and E-STP

• In-service patching for smooth software upgrade

• Passive backplane

• Redundancy backup for key components such as route processing modules, SFUs, and power modules to guard against a single point of failure

• Switching between components that hot back up each other, Graceful Restart (GR), NSF, NSR, and ISSU

• Hot swapping for all components

Intra- or inter-CGN service chassis 1+1 and 1:1 hot backup

QoS

• Provides a well-designed HQoS mechanism

• Provides advanced scheduling and congestion avoidance technologies, accurate traffic policing and traffic shaping, and complex rule definition and fine-grained flow identification

• Supports MPLS HQoS and ensures QoS for MPLS VPN, VLL, and PWE3 services

• Supports DiffServ- and MPLS TE-based DS-TE, eight Class Types (CTs), and TE-tunnel-based QoS

• Supports a maximum of 768K flow queues per slot

Value-added Service

• Supports Destination Address Accounting (DAA), which helps carriers identify services based on destination network segments and perform separate accounting for different services on IP bearer networks

Supports Enhanced Dynamic Service Gateway (EDSG), which identifies various user services based on traffic destination addresses and implements independent rate limit, accounting, and management for each service

Multicast

Supports the following:
