If graceful restart is supported (bgpRmEntRestartSupported is True), this field controls whether DC-BGP will act as a helper node only - its effect is to force BGP restart capabilities to be advertised to peers with no AFI/SAFIs listed. Peers will assume that this node can support the peer during graceful restart, but that this node will not retain any forwarding state if it restarts. This field can be changed while DC-BGP is active, but the new setting will not take effect until RM is restarted. The field should ony be set to True if the local node does not support Graceful Restart itself, so is not expected to change for an active node.
