Because PIM-SM cannot run without an RP, you must specify at least one C-RP in the domain.
With the Ethernet Routing Switch 5000 Series, you can configure only one local interface as a C-RP for any number of groups.
Using the GroupMask value, you can configure a C-RP for several groups in one configuration. For example, with a C-RP configuration with a GroupAddress value of 224.0.0.0 and a GroupMask of 240.0.0.0, you can configure the C-RP for a multicast range from 224.0.0.0 to 239.255.255.255.
Use the following procedure to configure a local PIM-SM interface as a candidate RP (C-RP).
Open one of the supported browsers.
Enter the IP address of the switch to open an EDM session.
The following table describes the fields of the Insert Candidate RP dialog box.
Field | Description |
---|---|
GroupAddress | Specifies the IP address of the multicast group. Together with the group mask, the group address identifies the prefix that the local router uses to advertise itself as a C-RP. |
GroupMask | Specifies the address mask of the multicast group. Together with the group address, the group mask identifies the prefix that the local router uses to advertise itself as a C-RP. |
RPAddress | Specifies the IP address of the C-RP. This address must be one of the local PIM-SM enabled interfaces. |
