Configuring SA Cache

An SA cache is used to save the (S, G) information carried in SA messages locally. When a device needs to receive multicast data, it directly obtains available (S, G) information from the SA cache.

Configuring the Maximum Number of (S, G) Entries in the Cache: Setting the maximum number of (S, G) entries in a Source Active (SA) cache can prevent Denial of Service (DoS) attacks.

Disabling the SA Cache Function: You are allowed to disable the Source Active (SA) cache function. Then, when a device wants to receive multicast data, it needs to wait for the SA message to be sent by its MSDP peer in the next period. This results in a delay in obtaining multicast data.
