多选题In which two ways does the BGP graceful restart capability preserve prefix information during a restart？（）AThe peer router sends an end-of RIB message to the restarting routerBThe peer router immediately removes the BGP routes that it learned from the restarting router from its BGP routing tableCThe restarting router does not remove any stale prefixes after the timer for stale entries expiresDThe 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 updatesEThe restarting router removes any stale prefixes after the timer for stale entries expires
