Version 7.5.1.0 Introduced on the E-Series.
Usage 
Information
FTOS counts the SA messages originated by itself and those received from the MSDP peers. 
When the total SA messages reach this limit, the subsequent SA messages are dropped (even 
if they pass RPF checking and policy checking).
If the total number of SA messages is already larger than the limit when this command is 
applied, those SA messages that are already in FTOS continue to be accepted. To enforce the 
limit in such situation, use the clear ip msdp sa-cache command.
