What is IP PIM sparse mode?

PIM Sparse Mode (PIM-SM) is a multicast routing protocol designed on the assumption that recipients for any particular multicast group will be sparsely distributed throughout the network. In other words, it is assumed that most subnets in the network will not want any given multicast packet.

What is PIM command?

PIM is a multicast routing architecture that allows the addition of IP multicast routing on existing IP networks. Multicast IP routing protocols are used to distribute data to multiple recipients.

How does PIM sparse work?

PIM-SM (PIM Sparse Mode) assumes that most hosts do not want to receive multicast traffic. It uses a nonflooding multicast model to direct traffic from the source to the interface when there are multicast receivers in the group. As a result, this model sends traffic only to the routers that specifically request it.

How to configure PIM multicast?

When configuring multicast, First step is enable multicast routing (ip multicast-routing [distributed]) CLI command. “distributed” keyword is required only on switch platforms (3750,3560,etc). Next step is to enable PIM (ip pim sparse-mode) on required layer 3 interfaces.

How do I restart PIM?

To restart the IPv6 Protocol Independent Multicast (PIM6) process, use the restart pim6 command. This command has no arguments or keywords. This command requires the Enterprise Services license. Enables flushing routes when the PIM6 process is restarted.

What is sparse mode vs dense mode?

One of the primary difference between Dense and Sparse mode is the multicast technique used. In Dense mode packets are flooded to the entire network and then branches where there are no receivers are eliminated. In Sparse mode packets branches distribution growth as new nodes join the multicast group.

How to configure a Cisco PIM?

Prerequisites for Configuring PIM

Before configuring PIM stub routing, you must have IP multicast routing configured on both the stub router and the central router. You must also have PIM mode (dense-mode, sparse-mode, or sparse-dense-mode) configured on the uplink interface of the stub router.

What is the difference between PIM Sparse Mode and SSM?

PIM-SM refers to PIM Sparse Mode. It is one of the modes under Any Source Multicast (ASM), where multicast streams can be received from any multicast source. PIM-SSM refers to PIM Source Specific Multicast, where the receiver can specify from which source it wants to receive a given multicast stream.

What is PIM passive mode?

PIM Passive allows you to specify that the interface is "passive" in regards to PIM. No PIM control packets are sent or processed (if received), but hosts can still send and receive multicast traffic and IGMP control traffic on the interface.

What is the role of the RP in PIM Sparse Mode?

PIM Sparse Mode uses a special router called a Rendezvous Point (RP) to connect the flow source or multicast tree to the router next to the wannabe receiver. The RP is typically used only temporarily, as we'll see below. There can be different RP's for different multicast groups, which is one way to spread the load.

What is IP PIM SSM range?

The SSM range is a range of addresses defined for use with the SSM model. By default the PIM SSM group range is 232.0. 0.0/8 for IPv4 and FF3x::/32 for IPv6.

What is IP multicast routing?

IP multicast routing enables a host (source) to send packets to a group of hosts (receivers) anywhere within the IP network by using a special form of IP address called the IP multicast group address.

What does IP PIM passive do?

If the ip pim passive command is configured on an interface enabled for IP multicast, the device will operate this interface in PIM passive mode, which means that the device will not send PIM messages on the interface nor will it accept PIM messages from other devices across this interface.

What is IP PIM SSM range?

The SSM range is a range of addresses defined for use with the SSM model. By default the PIM SSM group range is 232.0. 0.0/8 for IPv4 and FF3x::/32 for IPv6.

What is PIM passive mode?

PIM Passive allows you to specify that the interface is "passive" in regards to PIM. No PIM control packets are sent or processed (if received), but hosts can still send and receive multicast traffic and IGMP control traffic on the interface.

What is the role of the RP in PIM sparse mode?

PIM Sparse Mode uses a special router called a Rendezvous Point (RP) to connect the flow source or multicast tree to the router next to the wannabe receiver. The RP is typically used only temporarily, as we'll see below. There can be different RP's for different multicast groups, which is one way to spread the load.

What is PIM in firewall?

Protocol Independent Multicast (PIM) is a protocol for efficiently routing IP packets to multicast groups that may span throughout the internet. PIM provides dynamic multicast support on the appliance.

What is IP PIM DR priority?

You can configure the ip pim dr-priority command in either Dense mode (DM) or Sparse mode (SM). If more than one device has the same DR priority on a subnet (as in the case of default DR priority on all), the device with the numerically highest IP address on that subnet is elected as the DR.

What is show IP PIM neighbor?

show ip pim neighbors

Lists the IP address of a neighbor multicast router. VLAN, Lists the VLAN through which the routing switch connects to the indicated neighbor.
