圖中所示網(wǎng)絡(luò)運行RIPV2路由選擇協(xié)議,全網(wǎng)收斂并且所有的路由器運行正?!,F(xiàn)在R1的FastEthernet0/0端口,不能正常工作了,則網(wǎng)段內(nèi)的路由器會作出怎樣的回應(yīng)?()
A.所有的路由器會參照自己的拓撲數(shù)據(jù)庫,看它們是否有到192.168.1.0的備份路由。
B.R2和R3會標記到192.168.1.0的路由為不可用,并且不會從R1接受更新直到它們的抑制定時器超時
C.由于水平分割原則,R2不會向R1發(fā)送關(guān)于去往192.168.1.0網(wǎng)段的錯誤信息
D.當R2從R1那里學(xué)到192.168.1.0網(wǎng)段不可達時,R2把去往192.168.1.0網(wǎng)段的度量值設(shè)置為無限大,并向R1發(fā)送回應(yīng)消息。
E.R1將會發(fā)送LSA給R2和R3通知它們網(wǎng)絡(luò)的變化情況,然后所有的路由器周期性的遞增的發(fā)送更新直到網(wǎng)絡(luò)收斂。
