Changing the number of times the routing switch retries sending the same graft packet to join a flow

Syntax:

ip pim-dense [max-graft-retries[1-10]] 
 vlan[vid]ip pim-dense [max-graft-retries[1-10]]

Changes to the number of times the routing switch will retry sending the same graft packet to join a flow. If a graft ack response is not received after the specified number of retries, the routing switch ceases trying to join the flow. In this case the flow is removed until either a state-refresh from upstream re-initiates the flow or an upstream router floods the flow.

Increasing this value helps to improve multicast reliability.
