Configure Multicast Static Source Groups

Configure static source group entries in the Protocol Independent Multicast (PIM) multicast routing table. The PIM cannot prune these entries from the distribution tree.

Before you begin

Before you can configure a static source group, you must globally enable one of the following protocols:
- PIM-Sparse Mode (SM)
- PIM-Source Specific Multicast (SSM)

About this task

Even if no receivers exist in the group, the multicast stream for a static source group entry remains active.

The maximum number of static source groups must not exceed 1024.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Configure a static source group entry:

ip mroute static-source-group <A.B.C.D> <A.B.C.D/X>

Example

Create a static source group for two multicast groups: 224.32.2.1 and 226.50.2.2. The static source group for group 224.32.2.1 is for a source subnet 10.10.10.0/24. The static source group for group 226.50.2.2 is for the host 20.20.20.100/32.

Switch:1(config)#  ip mroute static-source-group 224.32.2.1 10.10.10.0/24 
Switch:1(config)#  ip mroute static-source-group 226.50.2.2 20.20.20.100/32

Variable definitions

Use the definitions in the following table to use the ip mroute static-source-group command.


Variable		Value
A.B.C.D		Specifies the IP address of the multicast group. Use the no operator to later remove this configuration.
A.B.C.D/X		Specifies the multicast source IP address and subnet mask for the static source group entry. You cannot create duplicate groups. How you configure the source address depends on the protocol and mode you use. Use the no operator to later remove this configuration.
