High Availability (HA)
Overview
High Availability (HA) in FTOS is configuration synchronization to minimize recovery time in the
event of a Route Processor Module (RPM) failure. The feature is available on the C-Series and
E-Series where noted by these symbols under command headings:
c e
FTOS on the E-Series supports RPM 1 + 1 redundancy. The Primary RPM performs all routing and
control operations, while the Secondary RPM is online and monitoring the Primary RPM.
In general, a protocol is defined as “hitless” in the context of an RPM failure/failover, and not failures
of a line card, SFM, or power module. A protocol is defined as hitless if an RPM failover has no impact
on the protocol.
Some protocols must be specifically enabled for HA, and some protocols are only hitless if related
protocols are also enabled as hitless (see the
