Ipv6 Pim-Ssm Overview - HP MSR2003 Configuration Manual

An IPv6 admin-scoped zone with a larger scope field value contains an IPv6 admin-scoped zone
with a smaller scope field value. The zone with the scope field value of E is the IPv6 global-scoped
zone. Table 20

IPv6 PIM-SSM overview

The ASM model includes IPv6 PIM-DM and IPv6 PIM-SM. The SSM model can be implemented by
leveraging part of the IPv6 PIM-SM technique. It is also called "IPv6 PIM-SSM."
The SSM model provides a solution for source-specific multicast. It maintains the relationship between
hosts and routers through MLDv2.
In actual applications, part of MLDv2 and IPv6 PIM-SM techniques are adopted to implement the SSM
model. In the SSM model, receivers have already located the IPv6 multicast sources. No RP or RPT is
required, and no source registration process is required for discovering IPv6 multicast sources in other
IPv6 PIM domains.
Neighbor discovery
IPv6 PIM-SSM uses the same neighbor discovery mechanism as IPv6 PIM-SM. For more information, see
"Neighbor discovery."
DR election
IPv6 PIM-SSM uses the same DR election mechanism as IPv6 PIM-SM. For more information, see
election."
