Which command restarts the TCP/IP subsystem？（）

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.

Previously cached values are retained by DB2, and after the restart, will be used for values 101 to 105. D . The next value will be 0 and DB2 will not ensure uniqueness between existing and newly generated values.
