No No No Yes If an active ESP experiences a
hardware or software event that
makes it unable to forward
traffic (such as a hardware
failure, an OIR, or a manual
switch) and a standby ESP is
configured, the standby ESP
becomes the active ESP with
the possibility of a minor
interruption (less than 200 ms).
Route Processor No No No Yes If an active RP experiences an
e
vent that makes it unable to
forward traffic (such as a
hardware failure, a software
failure, an OIR, or a manual
switch) and a standby RP is
configured, the standby RP
immediately becomes the active
RP.
SPA No No No No No standby configurations are
a
vailable for SPAs. If a SPA
fails, that particular SPA is
down and unable to forward
traffic.
In the event of a SPA shutdown,
all other SI
Ps and SPAs on the
router continue to be fully
operational.
SIP No No No No No standby configurations are
a
vailable for SIPs. If a SIP fails,
all SPAs in that SIP are down
