Related redundancy and reliability features include:

Redundant power supplies, host modules, host subsystems, and forwarding boards. For more information, see the JUNOS System Basics Configuration Guide and the JUNOS Hardware Network Operations Guide.
Additional link-layer redundancy, including Automatic Protection Switching (APS) for SONET interfaces, Multiplex Section Protection (MSP) for SDH interfaces, and DLSw redundancy for Ethernet interfaces. For more information, see the JUNOS Network Interfaces Configuration Guide.
Bidirectional Forwarding Detection (BFD) works with other routing protocols to detect failures rapidly. For more information, see the JUNOS Routing Protocols Configuration Guide.
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 JUNOS MPLS Applications Configuration Guide.
