Adds a multicast group address to the current C-RP configuration. Requires that the source IP VLAN (See
Specifying the source IP VLAN (optionally configuring multicast groups or range of groups)
on page 95) is
already configured. The
no
form of the command removes a multicast group address from the current C-RP
configuration.
This command does not enable or disable RP candidate operation.
NOTE:
An RP candidate supports up to four separate multicast address groups. If only one group-prefix
address exists in the router PIM configuration, you cannot delete it unless you first add another
group-prefix address.
Changing the C-RP hold-time
Hold-time is included in the advertisements the C-RP periodically sends to the domain's elected BSR, and
updates the BSR on how long to wait after the last advertisement from the reporting RP before assuming that it
has become unavailable.
Syntax:
rp-candidate hold-time [30-255]
Changes the hold time a C-RP includes in its advertisements to the BSR. Also, if C-RP is configured, but
disabled, this command re-enables it.
(Default: 150 seconds; Range: 30–255 seconds.)
Changing a C-RP's election priority
This priority is significant when multiple C-RPs in a given domain are configured to support one or more of the
same multicast groups.
Syntax:
rp-candidate priority [0-255]
Changes the current priority setting for a C-RP. Where multiple C-RPs are configured to support the same
multicast group(s), the candidate having the highest priority is elected. Zero (0) is the highest priority, and 255 is
the lowest priority.
(Default: 192)
Enabling, disabling, or changing router PIM notification
traps
Syntax:
[no] router pim trap [all | neighbor-loss | hardware-mrt-full | software-mrt-full]
Enables and disables the following PIM SNMP traps:
all
Enable/Disable all PIM notification traps.
(Default: Disabled)
