Enabling Pim On An Interface; Setting A Priority To Determine The Designated Router - Juniper JUNOSE 11.0.X MULTICAST ROUTING Configuration Manual

JUNOSe 11.0.x Multicast Routing Configuration Guide

Enabling PIM on an Interface

You can enable PIM on an interface in one of the allowed modes and specify how
often the interface sends hello messages to neighbors.
You can configure PIM and MLD on the same interface. If you configure MLD and
PIM on an interface, the router considers that PIM owns the interface.

ipv6 pim sparse-mode
ipv6 pim sparse-mode graceful-restart-duration

Setting a Priority to Determine the Designated Router

You can influence whether a particular router is selected as the designated router
with the ipv6 pim dr-priority command. A higher priority value increases the
likelihood that a router is selected as the designated router, while a lower value
decreases the likelihood. The ipv6 pim dr-priority command in Router Configuration
mode sets the designated router priority on all the PIM interfaces on the router. To

Enabling PIM on an Interface

Use the no version to reenable PIM processing.
See pim disable.
Use to specify how often the router sends hello messages to neighbors.
Example
host1(config-if)#ipv6 pim query-interval
Use the no version to restore the default setting, 30 seconds.
See ipv6 pim query-interval.
Use to enable PIM in sparse mode on an interface.
Example
host1(config-if)#ipv6 pim sparse-mode
Use the no version to disable PIM in sparse mode on an interface.
See ipv6 pim sparse-mode.
Use to set the graceful restart duration for PIM sparse mode.
Example
host1(config-if)#ipv6 pim sparse-mode graceful-restart-duration 10
Use the no version to return to the default duration of 30 seconds.
See ipv6 pim sparse-mode.
