ID 沖突 描述錯誤的是： 時，要設(shè)置DC 位，每隔120s 間隔發(fā)送一次HELLO 報文，用于檢測鄰居，不再發(fā)送HELLO 報文，即始終認(rèn)為對端鄰居處于活動狀態(tài)，LSA 每隔30min 需要進(jìn)行一次刷新 age 字段描述正確的是：（請選擇2 個答案） age 的單位為秒，在LSDB 中的LSA 的LS age 隨時間增長而減少 age 的單位為秒，在LSDB 中的LSA 的LS age 隨時間增長而增長 的LS age 達(dá)到了LSRefreshTime(30min)，這條LSA 的生產(chǎn)者需要重新生成一個該LSA的實例 的LS age 達(dá)到了LSRefreshTime(30min)，任意一臺路由器都可
