Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information The system counts the SA messages originated by itself and those messages 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 the software continue to be accepted. To enforce the limit in such situation, use the
clear ip msdp sa-cache command.
