Version Description
9.11.3.0 Introduced on the Z9100-ON, S4048-ON, S6000-ON, S6100-ON, S4048T-ON,
S3100, S6010-ON, S3048-ON, and C9010.
Usage
Information
This command configures an expiration timer for all S.G entries, unless they are assigned to an Extended
ACL.
Even though the FHR nodes act as RPs, these nodes still send Register encap messages to themselves
and expect to receive a Register stop message (for Anycast RP support). As a result, if the DLT timer
expires, SG is not deleted until the register state is deleted in the node. This register state expires 210
seconds after the last Null register is received.
ipv6 pim spt-threshold
Specifies when a PIM leaf router should join the shortest path tree.
Syntax
ipv6 pim [vrf vrf-name] spt-threshold {infinity}
To return to the default value, use the no ipv6 pim spt-threshold command.
Parameters
vrf vrf-name (OPTIONAL) Enter the keyword vrf followed by the name of the VRF to view IP
PIM debugging messages corresponding to that VRF.
NOTE: Applies to specific VRF if input is provided, else applies to Default VRF.
infinity Enter the keyword infinity to have all sources for the specified group use the
shared tree and never join shortest path tree (SPT).
Defaults Not configured.
