The BGP session to the 10.3.3.3 neighbor is established, but the router has not received any BGP routing updates from the 10.3.3.3 neighbor.B. The router is attempting to establish a BGP peering session with the 10.2.2.2 neighbor.C. The router is attempting to establish a BGP peering session with the 10.1.1.1 neighbor.D. The BGP session to the 10.3.3.3 neighbor is established.E. The BGP session to the 10.2.2.2 neighbor is established.F. The BGP session to the 10.1.1.1 neighbor is established.

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 routerB、The peer router immediately removes the BGP routes that it learned from the restarting router from its BGP routing tableC、The restarting router does not remove any stale prefixes after the timer for stale entries expiresD、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 updatesE、The restarting router removes any stale prefixes after the timer for stale entries expires

What are the two benefits of graceful restart？（）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.

Which two features must be configured to perform AToM NSF？（）A、FRRB、SSOC、distribute CEFD、switch virtual pathE、graceful restart
