In which two ways does the BGP graceful restart capability preserve prefix information during a
restart? (Choose two.)
A.
The peer router sex`outer.
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.
