No SA entries exist in the device's SA message cache
Symptom
MSDP fails to send (S, G) entries through SA messages.
Solution
To resolve the problem:
Use the display ip routing-table command to verify that the unicast route between the devices is reachable.
Verify that a unicast route is available between the two devices that will become MSDP peers to each other.
Verify the configuration of the import-source command and its ipv4-acl-number argument, and make sure the ACL rule filters appropriate (S, G) entries.
If the problem persists, contact Hewlett Packard Enterprise Support.
