IGMP Configuration Guidelines

To configure IGMP, you include statements at the [edit protocols igmp] hierarchy level of the configuration:

 protocols {
 	 igmp {
 	 	 traceoptions {
 	 	 	 file name <replace> <size size> <files number> <no-stamp> 
 	 	 	 	 <(world-readable | no-world-readable)>;
 	 	 	 flag flag <flag-modifier> <disable>; 
 	 	 }
 	 	 interface interface-name {
 	 	 	 disable; 
 	 	 	 query-interval seconds; 
 	 	 	 query-last-member-interval seconds; 
 	 	 	 query-response-interval seconds; 
 	 	 	 robust-count number; 
 	 	 	 version version; 
 	 	 }
 	 } 
 } 
 

By default, IGMP is automatically enabled on all interfaces on which you configure DVMRP or PIM.

This chapter describes the following tasks for configuring IGMP:

• Minimum IGMP Configuration
• Enable IGMP
• Modify the IGMP Host-Query Message Interval
• Modify the IGMP Query Response Interval
• Modify the Last-Member Query Interval
• Modify the Robustness Variable
• Change the IGMP Version
• Trace IGMP Protocol Traffic
