hello-multiplier
Syntax hello-multiplier deci-units
no hello-multiplier
Context config>service>vprn>pim>interface
Description This command configures the multiplier to determine the holdtime for a PIM neighbor.
The hello-multiplier in conjunction with the hello-interval determines the holdtime for a PIM
neighbor.
Parameters
deci-units — Specify the value, specified in multiples of 0.1, for the formula used to calculate the
improved-assert
Syntax [no] improved-assert
Context config>service>vprn>pim>interface
Description
This command enables improved assert processing on this interface. The PIM assert process
establishes a forwarder for a LAN and requires interaction between the control and forwarding
planes.
The assert process is started when data is received on an outgoing interface. This could impact
performance if data is continuously received on an outgoing interface.
When enabled, the PIM assert process is done entirely on the control-plane with no interaction
between the control and forwarding plane.
Default
enabled
max-groups
Syntax max-groups value
no max-groups
Context config>service>vprn>pim>interface
Description This command configures the maximum number of groups for which PIM can have downstream state
based on received PIM Joins on this interface. This does not include IGMP local receivers on the
interface. When this configuration is changed dynamically to a value lower than the currently
accepted number of groups, the groups that are already accepted are not deleted. Only new groups
will not be allowed. When this object has a value of 0, there is no limit to the number of groups.

hello-holdtime based on the hello-multiplier:
(hello-interval * hello-multiplier) / 10
This allows the PIMv2 default timeout of 3.5 seconds to be supported.
Values 20 — 100
