A.Graceful restart allows session information recovery without disruption to the network.
B.A node can perform a graceful restart to help a neighbor recover its state. The label bindings are kepton state information， which helps the failed node recover faster and does notaffect the current for wardtraffic.
C.Graceful restart allows a node to recover state from its neighbor when there is no RP or before thedevice undergoes SSO.
D.Graceful restart does not allow session information recovery.
E.During a graceful restart， the router removes any stale prefixes after a timer for stale entries expires
