In BGP routing， what does the rule of synchronization mean？（）

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. When the neighboring routers send end-of-RIB messages to indicate that they are donesending updates，the restarting router starts sending its own updates. C . The peer router sends an end-of-RIB message to the restarting router. D . The restarting router removes any stale prefixes after the timer for stale entries expires. E . The restarting router does not remove any stale prefixes after the timer for stale entries expires.

BGP route-reflector will stop reflecting the routes if they’re not directly-connected clients D . None of the above

A . It will advertise the prefix to all other client peers and non-client peers. B . It will not advertise the prefix to EBGP peers. C . It will only advertise the prefix to all other IBGP peers. D . It will not advertise the prefix to any peers.
