Additional Features

We've extended support for the following features to these platforms.

• BFD support (ACX7100-32C and ACX7100-48L)—

  Starting in Junos OS Evolved Release 21.3R1, you can configure BFD over label-switched paths (LSPs) or RSVP-based LSPs in a centralized mode.

  [See Bidirectional Forwarding Detection (BFD) for MPLS.]

• Control plane distributed denial of service (DDoS) protection (ACX7100-32C and ACX7100-48L)

  [See Control Plane Distributed Denial-of-Service (DDoS) Protection Overview.]

• Disabling local switching in bridge domains (ACX7100-32C and ACX7100-48L)

  [See Configuring MAC Address Flooding and Learning for VPLS.]

• Ethernet ring protection switching (ERPS) with G.8032 version 2 (ACX7100-32C and ACX7100-48L)

  [See Understanding Ethernet Ring Protection Switching Functionality.]

• Firewall filter protocols (MPLS, CCC, virtual private LAN service (VPLS), and ANY) (ACX7100-32C and ACX7100-48L)

  [See Firewall Filters Overview.]

• IEEE 802.1ag Operation, Administration, and Maintenance (OAM) CFM (ACX7100-32C and ACX7100-48L)

  [See IEEE 802.1ag OAM Connectivity Fault Management Overview.]

• Layer 2 VPN and Layer 2 circuit support (ACX7100-32C and ACX7100-48L):
  • L2 circuit—Targeted LDP signaling pseudowires and interoperability between different types of supported attachment circuit (AC) for L2 circuit
  • L2 VPN circuit—BGP signaling
  • MPLS fast reroute (FRR) on IGP, circuit attachment types (port, VLAN, and Q-in-Q tunneling), control word, pseudowire circuit on aggregated Ethernet interfaces, indirect next hops and composite next hops, pipe and uniform mode time-to-live (TTL)., Tag Protocol Identifiers (TPIDs), and VLAN map on pop, push, or swap

  [See Understanding Layer 2 VPNs and Configuring Interfaces for Layer 2 Circuits.]

• Logical interfaces support classification and rewrite rules for MPLS, VPLS, Layer 3 VPN, Layer 2 Circuit, CCC, IRB, and EVPN (ACX7100-32C and ACX7100-48L)

  [See Classifiers and Rewrite Rules at the Global, Physical, and Logical Interface Levels Overview.]

• Optical interfaces, transceivers, and direct attach copper (DAC) cables (ACX7100-32C and ACX7100-48L)

  [See Hardware Compatibility Tool.]

• Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), and VLAN Spanning Tree Protocol (VSTP) (ACX7100-32C and ACX7100-48L)

  [See Spanning-Tree Protocol Overview.]

• Segment routing support (ACX7100-32C and ACX7100-48L):
  • Segment routing global block (SRGB) for OSPF and IS-IS
  • Fast reroute
  • Metro Ethernet services over segment routing infrastructure
  • Segment routing services- L3VPN, IPv6 VPN Provider Edge (6VPE) , IPv6 Provider Edge (6PE), Layer 2 VPN, Layer 2 Circuit, and BGP-VPLS
  • Static segment routing (node segment, prefix segment, adjacency, and anycast segments) for OSPF and IS-IS
  • Topology independent loop-free alternate (TI-LFA) with segment routing for OSPF and IS-IS

  [See Understanding Topology-Independent Loop-Free Alternate with Segment Routing for IS-IS, Understanding Source Packet Routing in Networking (SPRING), and Understanding Adjacency Segments, Anycast Segments, and Configurable SRGB in SPRING.]

• Storm control (ACX7100-32C and ACX7100-48L , and QFX5700)

  [See Understanding Storm Control]

• Virtual private wire service (VPWS) with EVPN signaling mechanisms and flexible cross-connect (FXC) support (ACX7100-32C and ACX7100-48L)

  By default, control-word is enabled on these platforms. To disable the control word feature, use the set routing-instances routing-instance-name protocols evpn no-control-word command.

  [See Overview of VPWS with EVPN Signaling Mechanisms.]

• VRRP for IPv4 and IPv6 (ACX7100-32C and ACX7100-48L)

  [See VRRP and VRRP for IPv6 Overview.]
