Features and Benefits
High Availability
QFX10000 modular spine and core switches deliver a number of
high availability features that ensure uninterrupted, carrier-class
performance. Each QFX10000 chassis includes an extra slot to
accommodate a redundant RE module that serves as a backup in
hot-standby mode, ready to take over in the event of a primary RE
failure. If the primary RE fails, the integrated Layer 2 and Layer 3
graceful Routing Engine switchover (GRES) feature of Junos OS,
working in conjunction with the nonstop active routing (NSR) and
nonstop bridging (NSB) features, ensures a seamless transfer of
control to the backup, maintaining uninterrupted access to
applications, services, and IP communications.
