Administrator Guide

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.
