What does IP PIM Sparse Mode do?
A Protocol Independent Multicast (PIM) sparse-mode domain uses reverse-path forwarding (RPF) to create a path from a data source to the receiver requesting the data. When a receiver issues an explicit join request, an RPF check is triggered. 0.13) by means of each router’s RPF interface until it reaches the RP.
Which user can enable PIM?
For Azure AD roles in PIM, only a user who is in the Privileged Role Administrator or Global Administrator role can manage assignments for other administrators. Global Administrators, Security Administrators, Global Readers, and Security Readers can also view assignments to Azure AD roles in PIM.
What is difference between ASM and SSM?
In ASM, receivers express interest only in a given multicast group address. In contrast, with Source-Specific Multicast (SSM) the specific source(s) that may send traffic to the group are known in advance. In SSM, receivers express interest both in a given multicast address and specific associated source address(es).
What is IP Multicast boundary?
The IP multicast boundary feature is designed to selectively allow or disallow multicast flows to configured interfaces. The ip multicast-boundary command allows you to configure a boundary on a PIM enabled interface by defining which multicast groups may not forward packets over a specified interface.
How does a PIM Sparse Mode domain work?
A Protocol Independent Multicast (PIM) sparse-mode domain uses reverse-path forwarding (RPF) to create a path from a data source to the receiver requesting the data. When a receiver issues an explicit join request, an RPF check is triggered. A (*,G) PIM join message is sent toward the RP from the receiver’s designated router (DR).
How does Multicast PIM Sparse Mode work on a router?
Since we are using PIM sparse mode, this router will have to forward the multicast traffic to the RP. Instead of forwarding everything, R1 will only send the first multicast packet. This packet is encapsulated in a PIM register message and forwarded to the RP. Once the RP receives the PIM register message there are two options:
When does PIM Sparse router send a PIM Join message?
To summarize this, PIM sparse routers will send a PIM join message when: The router has received an IGMP membership report from a host on a directly connected interface. The router has received a PIM join from a downstream router. When the RP receives the PIM join, it will start forwarding the multicast traffic.
How to statically configure a PIM-SM router?
Option:Use rp-address ip-addr [group-addr/group-mask]to statically configure the router as the RP for a specific multicast group or range of multicast groups. (This must be configured on all RIM-SM routers in the domain.) Option: In the PIM router context, change one or more of the traffic control settings.
