Fix Recommendation

Configure the multicast router to increase the SPT threshold or set it to infinity to minimalize (S, G) state within the multicast topology where ASM is deployed.

Check Contents

Review the multicast last-hop router configuration to verify that the SPT switchover threshold is increased (default is "0") or set to infinity (never switch over).

If any multicast router is not configured to increase the SPT threshold or set to infinity to minimalize (S, G) state, this is a finding.
