Changing the randomized delay setting for PIM-SM neighbor notification


ip pim-sparse hello-delay [0-5] 
 vlan [vid] ip pim-sparse hello-delay [0-5]

Changes the maximum time in seconds before the router actually transmits the initial PIM hello message on the current VLAN. In cases where a new VLAN activates with connections to multiple routers, if all of the connected routers sent hello packets at the same time, the receiving router could become momentarily overloaded. This value randomizes the transmission delay to a time between 0 and the hello delay setting. Using 0 means no delay.

After the router sends the initial hello packet to a newly detected VLAN interface, it sends subsequent hello packets according to the current Hello Interval setting.

Not used with the no form of the ip pim command.

(Default: 5 seconds)
