I am using the PIMD daemon on Ubuntu Server 12.0.4 (32-bit). When it receives IGMPv2 membership report for certain group, it takes sometimes two, sometimes five seconds to send PIM join message to its Cisco 2811 PIM-SM enabled neighbor. Has anybody any idea why the time between these two actions is so variable and long? For example, when the PIM-SM enabled Cisco 2811 receives IGMP membership report it sends the PIM join message immediately (in tens, max. hundreds of milliseconds).
