PIM-SM (Sparse Mode)
Configuring PIM-SM on the Router
Syntax: router pim rp-address < rp-ip-addr > < group-addr/group-mask > [override]
[no] router pim rp-address < rp-ip-addr > < group-addr/group-mask>
[override]
< rp-ip-addr >: Statically specifies the IP address of the interface
to use as an RP. Up to four static-RP IP addresses can be
configured. (Each address can be entered multiple times for
different multicast groups or group ranges.)
< group-addr/group-mask >: Specifies the multicast group or
range of contiguous groups supported by the statically
configured RP.
[override]: Where a static-RP and a C-RP are configured to
support the same multicast group(s) and the multicast group
mask for the static RP is equal to or greater than the same
mask for the applicable C-RPs, this command assigns the
higher precedence to the static-RP, resulting in the C-RP
operating only as a backup RP for the configured group.
Without override, the C-RP has precedence over a static-RP
configured for the same multicast group(s).
Example of Configuring PIM-SM Support in the
Router PIM Context
This example assumes the following:
■ IP routing, IP multicast-routing, and at least one routing method (RIP,
OSPF, and/or static IP routes) are already configured in the global config­
uration context
.
■ An IP routing method (RIP or OSPF) and PIM-sparse are already config­
ured in the static VLAN context on which you want to support PIM-SM
operation.
N o t e Routers configured for C-RP operation can also be configured for C-BSR
operation.
Use of static-RP operation must be identically configured on all PIM-SM
routers in the domain.
