High-Availability Features
●
High System Availability - The RSP supports the HSA feature, which allows two RSPs to be used simultaneously with the HSA feature
enabled and configured. With the HSA feature, one RSP operates as the active processor and the other RSP operates as the standby
processor, which takes over and reboots the system if the active RSP fails. In addition, the Cisco 7500 supports redundancy of power
supplies.
●
Cisco 7500 Single Line Card Reload - The Single Line Card Reload (SLCR) feature isolates a fault in one VIP from the rest of the system. It
allows the system to reload only the line card that has failed, without affecting the work of the other line cards. This feature dramatically
reduces total outage time and impact.
●
Cisco 7500 Route Processor Redundancy+ - The RPR+ feature is an enhancement to the RPR feature. RPR+ further accelerates RSP
switchover (down to only 30-40 seconds) compared to RPR. Also, it keeps the line cards from being reset and reloaded when an RSP
switchover occurs.
●
Cisco 7500 Fast Software Upgrade - The Fast Software Upgrade (FSU) feature reduces planned downtime; this feature is based on the same
mechanism as RPR. It allows users to configure the system to switch over to a standby RSP, which is preloaded with a different image from
that running on the active RSP.
●
Cisco 7500 stateful switchover - This feature, which is based on RPR+, allows the active RSP to pass the necessary state information of key
routing and interface protocols to the standby RSP upon switchover, thereby reducing the time for the standby RSP to learn and converge
routes.
●
Cisco 7500 Non-stop forwarding - Also based on RPR+, Non-Stop Forwarding allows routers with redundant RSPs to continue forwarding
data to the standby RSP during a switchover. This feature uses the Forwarding Information Base (FIB) that was current at the time of the
switchover. Once the routing protocols have converged, the FIB table is updated and stale route entries are deleted. This feature eliminates
downtime during the switchover.
