hardware-specific and software-specific methods to ensure minimal downtime and
ultimately improve the performance of your network.
For hardware components, Juniper Networks provides redundancy solutions to ensure
that the router continues to operate in the event of a hardware fault. This redundancy
can exist on various router models in the form of multiple power supplies, cooling fans,
switching planes, routing engines and, in some cases, interfaces. Redundancy also allows
for hot-swapping various components within your Juniper Networks router.
NOTE: For information about E Series hardware redundancy features, see
the ERX Hardware Guide or the E120 and E320 Hardware Guide.
Stateful SRP Switchover Redundancy Modes on page 37
Stateful SRP Switchover States on page 38
Application Support for Stateful SRP Switchover on page 42
Stateful SRP switchover is supported on all E Series routers except for the ERX310
Broadband Services Router.
For information about the modules supported on E Series routers:
See the ERX Module Guide for modules supported on ERX7xx models and ERX14xx
models.
See the E120 and E320 Module Guide for modules supported on the E120 and E320
Broadband Services Routers.
The following table lists which SRPs support or do not support the high availability mode
(stateful SRP switchover) feature.
