Refer to the exhibit. Which of the following statements is true? ()
A. BGP NSF awareness is enabledB. SSO for BGP NSF capability is enabledC. BGP graceful restart awareness is enabledD. 10.11.1.187 is configured as an NSF-capable BGP neighbor
考题
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. The label bindings are kepton state information， which helps the failed node recover faster and does notaffect the current for wardtraffic.C、Graceful restart allows a node to recover state from its neighbor when there is no RP or before thedevice undergoes SSO.D、Graceful restart does not allow session information recovery.E、During a graceful restart， the router removes any stale prefixes after a timer for stale entries expires

考题
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. 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协议为了支持GR，做了如下扩展（）。A、在BGP的OPEN消息中，增加了一种表示GR的能力，称为Graceful Restart Capability。这种能力被BGP用来向邻居表示其支持Graceful restart的能力B、在Keepalive报文中增加TLV211表明路由器发生了重启C、定义了两个重要的定时器：Restart timer和Wait-For-EOR timerD、在Update报文中，新增加一个EOR（End-of-RIB）标志，用于表明路由信息向邻居更新完毕
