Configure Global IPv6 PIM-SM Properties

Before you begin

Note

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

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Configure the timeout to discard data:

    ipv6 pim disc-data-timeout <5-65535>

  3. Configure the forward cache timeout:

    ipv6 pim fwd-cache-timeout <10-86400>

  4. Configure the interval for join and prune messages:

    ipv6 pim join-prune-interval <1-18724>

  5. Specify how long to suppress register messages:

    ipv6 pim register-suppression-timeout <10-65535>

  6. Configure PIM Infinite Threshold Policy:

    ipv6 pim spt-infinite-threshold

  7. Configure the polling interval for the routing table manager (RTM):

    ipv6 pim unicast-route-change-timeout <2-65535>

  8. Configure the PIM mode:

    ipv6 pim mode <sparse> <ssm>

  9. 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.
