R3303-HP HSR6800 Routers IP Multicast Configuration Guide

Configuration prerequisites
Before you configure IGMP snooping port functions, complete the following tasks:
• Enable IGMP snooping in the VLAN.
• Configure the corresponding port groups.
• Determine the aging timer for dynamic router ports.
• Determine the aging timer for dynamic member ports.
• Determine the multicast group and multicast source addresses.
Setting aging timers for dynamic ports
If a router receives no IGMP general queries or PIM hello messages on a dynamic router port when the
aging timer of the port expires, the router removes the port from the router port list.
If the router receives no IGMP reports for a multicast group on a dynamic member port when the aging
timer of the port expires, the router removes the port from the multicast forwarding entry for that multicast
group.
If the memberships of multicast groups change frequently, you can set a relatively small value for the
aging timer of the dynamic member ports. If the memberships of multicast groups change rarely, you can
set a relatively large value.
