The administrative state of this entry.
When the status of this object is set to 'adminStatusDown', the
router is removed from the corresponding anycast rendezvous
point set. This MAY cause the TIB to be updated.
When the status of this object is set to 'adminStatusUp', the
router is added to the anycast rendezvous point and will start
handling PIM messages. This MAY cause the TIB to be updated.
Note: If the status is set to 'adminStatusDown' and the
pimAnycastRPSetLocalRouter object is 'true' (this entry
corresponds to the local router), the entire set is
invalidated. The Anycast-RP Set is only valid if the
local router is a member of the set.
