Configure Global IPv6 PIM-SM Properties

Before you begin

Note

Before you can enable the PIM Infinite Threshold Policy feature, you must first disable the following:

PIM-SM
PIM-SSM

About this task

Use this procedure to configure the global IPv6 PIM-SM parameters on the switch.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Configure the timeout to discard data:

ipv6 pim disc-data-timeout <5-65535>
Configure the forward cache timeout:

ipv6 pim fwd-cache-timeout <10-86400>
Configure the interval for join and prune messages:

ipv6 pim join-prune-interval <1-18724>
Specify how long to suppress register messages:

ipv6 pim register-suppression-timeout <10-65535>
Configure PIM Infinite Threshold Policy:

ipv6 pim spt-infinite-threshold
Configure the polling interval for the routing table manager (RTM):

ipv6 pim unicast-route-change-timeout <2-65535>
Configure the PIM mode:

ipv6 pim mode <sparse> <ssm>
Verify the configuration changes:

show ipv6 pim

Example

Verify the configuration changes:

Switch:1#show ipv6 pim

Variable Definitions

The following table describes the variables for the ipv6 pim command.


Variable	Value
disc-data-timeout <5-65535>	Specifies the duration in seconds to discard data until the switch receives the join message from the rendezvous point (RP). An IP multicast discard record is created after a register packet is sent, until the timer expires or the switch receives a join message. The default value is 60.
enable	Enables PIM globally on the switch. The default is disabled.
fwd-cache-timeout <10-86400>	Specifies the forward cache timeout value. The default value is 120.
join-prune-interval <1-18724>	Specifies the duration in seconds before the PIM router sends out the next join or prune message to its upstream neighbors. The default value is 60.
mode <sparse> <ssm>	Configures PIM mode on the switch. The default value is sparse.
register-suppression-timeout <10-65535>	Specifies the duration in seconds the designated router (DR) suppresses sending registers to the RP. The timer starts after the DR receives a register-stop message from the RP. The default value is 60.
spt-infinite-threshold	Enables PIM Infinite Threshold Policy for IPv6, so that multicast traffic follows the shared tree path through a Rendezvous Point (RP) instead of automatically switching over to shortest path tree (SPT). The default is disabled.
static-rp	Add new static-rp entries and enable static-rp.
unicast-route-change-timeout <2-65535>	Specifies the duration in seconds the switch polls the RTM for unicast routing information updates for PIM. The default value is 5.
