High Availability-Related Features in Junos OS

Related redundancy and reliability features include:

  • Redundant power supplies, host modules, host subsystems, and forwarding boards. For more information on your specific device, see the Junos Documentation by Product.

  • Additional link-layer redundancy, including Multiplex Section Protection (MSP) for SDH interfaces, and DLSw redundancy for Ethernet interfaces. For more information, see the Ethernet Interfaces User Guide for Routing Devices.

  • Bidirectional Forwarding Detection (BFD) works with other routing protocols to detect failures rapidly. For more information, see the Understanding How BFD Detects Network Failures.

  • Redirection of Multiprotocol Label Switching (MPLS) label-switched path (LSP) traffic—Mechanisms such as link protection, node-link protection, and fast reroute recognize link and node failures, allowing MPLS LSPs to select a bypass LSP to circumvent failed links or devices. For more information, see the MPLS Applications User Guide.
