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.
