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).
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. |
