多項選擇題In which two ways does the BGP graceful restart capability preserve prefix information during a restart?()

A.The peer router sends an end-of RIB message to the restarting router
B.The peer router immediately removes the BGP routes that it learned from the restarting router from its BGP routing table
C.The restarting router does not remove any stale prefixes after the timer for stale entries expires
D.The router establishes BGP sessions with other routers and relearns the BGP routes from other routers that are also capable of graceful restart. The restarting router waits to receive updates from the neighboring routers. When the neighboring routers send end-of-RIB messages to indicate that they are done sending updates, the restarting router starts sending its own updates
E.The restarting router removes any stale prefixes after the timer for stale entries expires
