In which two ways does the BGP graceful capability preserve prefix information during a restart？（）A、The peer router immediately removes the BGP routers that it learned from the restarting router from itsBGP routing tables.B、The router establishes BGP sessions with other routers and relearns the BGP routes from others that are also capable of graceful restart. The restarting router waits to receive updates from the neighboringrouters.
