Usage Guidelines

Usage Scenario

After the SA cache function is enabled, you can run the display msdp sa-count command to display statistics about the (S, G) entries in the SA cache.

Prerequisites

The SA cache function has been enabled. By default, the SA cache function is enabled.

Precautions

If neither vpn-instance vpn-instance-name nor all-instance is specified, the command displays cached (S, G) entries in the public network instance.
