If a large number of hosts need the information, the information - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 9
Unicast and broadcast techniques cannot provide point-to-multipoint data transmissions with the minimum network consumption. Multicast transmission can solve this problem.

Based on the implementation mechanism, Mode for IPv6 (IPv6 PIM-SM) In this document, an IPv6 PIM domain refers to a network composed of IPv6 PIM routers. IPv6 PIM-DM overview IPv6 PIM- - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 146
• Assert Neighbor discovery In an IPv6 PIM domain, each interface that runs IPv6 PIM on a router periodically multicasts IPv6 PIM hello messages to all other IPv6 PIM routers on the local subnet to discover IPv6 PIM neighbors, maintain IPv6 PIM neighboring relationship with other routers, and build - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 147
the node that sent a graft message does not receive a graft-ack message from its upstream node, it continues to send graft messages at a configurable interval until it receives an acknowledgment from its upstream node. On a subnet with more than one multicast router, the assert mechanism shuts off - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 148
point trees (RPTs). An RPT is rooted at a router that has been configured as the rendezvous point (RP) for an IPv6 multicast group, and the more information, see "Neighbor discovery." DR election On a shared-media LAN like Ethernet, only a DR forwards IPv6 multicast data. A DR is required in both - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 149
in the priority, or if any router in the network does not support carrying the DR-election priority in hello messages, the router with the dynamically elect RPs. An elected RP provides services for a different IPv6 multicast group. For this purpose, you must configure a bootstrap router (BSR). A BSR - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 150
RP address from an IPv6 multicast group address to map the IPv6 multicast group to an RP. This RP can take the place of the configured static RP or the RP dynamically elected by the bootstrap mechanism. A DR does not need to learn the RP address beforehand. The specific process is - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 151
the receiver-side DR. 2. After getting the receiver information, the DR sends a join message, which is forwarded hop by hop to the RP that provides services for the IPv6 multicast group. 3. The routers along the path from the DR to the RP form an RPT branch. Each router on this branch - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 152
from unnecessarily encapsulating the data. Switchover to SPT CAUTION: If the switch is an RP, disabling switchover to SPT might cause multicast traffic In an IPv6 PIM-SM domain, only one RP and one RPT provide services for a specific IPv6 multicast group. Before the switchover to SPT occurs, the - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 153
. Zone border routers (ZBRs) form the boundary of an IPv6 admin-scoped zone. Each IPv6 admin-scoped zone maintains one BSR to provide services for IPv6 multicast groups with the same scope field value. IPv6 multicast protocol packets, such as assert messages and BSMs, of these IPv6 multicast - HP 6125XLG | R2306-HP 6125XLG Blade Switch IP Multicast Configuration Guide - Page 154
as private group addresses. The IPv6 global-scoped zone can be regarded as a special IPv6 admin-scoped zone, and it maintains a BSR to provide services for the IPv6 multicast groups with the scope field value as 14.
