which redundancy mode between two sup720-3B with different memory
I have a R7600 with one active sup720-3B(512MB SP and 512MB RP Memory). So can I install one more sup720-3B(1GB SP and 1GB RP) for standby role? And which redundancy mode (RPR, RPR+ or SSO) when I install both supervisors on R7600?
In NSF/SSO mode, one MSFC is active and the other MSFC is in a hot-standby mode. The hot-standby MSFC maintains a constant readiness state by receiving state information from the active MSFC. At any given moment, the standby MSFC may be called on by the supervisor engine to take over the responsibilities held by the active MSFC.
-In the above state, you can still access or session into standby MSFC.
In RPR mode, the startup configuration is synchronized to the standby MSFC, however, it is not processed in any way until the switchover occurs. The running configuration is not synchronized to the standby MSFC.
