Additional Sparse Mode Settings

Specifying the Rendezvous Point

1. Select the PIM component that will represent the RP candidate:
2. Configure the IPv4 address of the switch interface which will be advertised as a
candidate RP for the specified multicast group:
3. If using dynamic RP candidates, configure the amount of time that the elected
interface will remain the RP for the group before a re‐election is performed:
Static RP
1. Enable static RP configuration.
2. Select the PIM component that will represent the RP candidate:
3. Configure the static IPv4 address.

Influencing the Designated Router Selection

Using PIM‐SM, at least one PIM‐capable router must be a candidate for use as a
Rendezvous Point (RP) for any given multicast group. If desired, the G8264 can act
as an RP candidate. To assign a configured switch IP interface as a candidate, use
the following procedure.
RS G8264(config)# ip pim component <1‐2>
RS G8264(config­ip­pim­comp)# rp­candidate rp­address <group address>
<group address mask> <candidate IPv4 address>
The switch interface will participate in the election of the RP that occurs on the
Bootstrap Router, or BSR (see "Specifying a Bootstrap Router" on page
RS G8264(config­ip­pim­comp)# rp­candidate holdtime <0‐255>
RS G8264(config­ip­pim­comp)# exit
If RP no election is desired, the switch can provide a static RP. Use the following
commands:
RS G8264(config)# ip pim static­rp enable
RS G8264(config)# ip pim component <1‐2>
RS G8264(config­ip­pim­comp)# rp­static rp­address <group address> <group address
mask> <static IPv4 address>
Using PIM‐SM, All PIM‐enabled IP interfaces are considered as potential
Designate Routers (DR) for their domain. By default, the interface with the highest
IP address on the domain is selected. However, if an interface is configured with a
