然后是路由器 B：

通過 RIP 得到的路由用一個 R 來標記。
要注重的是，通過路由器 A 和路由器 B 的廣播，Zebra 現在知道了 10.0.0.0/24 和 10.0.1.0/24 兩個網段。測試時，我們從 ThinkPad Zebra 路由器上 ping 10.0.0.1 和 10.0.1.1，并從兩個路由器上 ping 10.0.2.1（ThinkPad 的虛擬網絡接口）。
為了測試路由的 failover，我們把連接網段 10.0.0.0/24 的路由器 A 上的網絡連接斷開。經過總計約兩分鐘的過期時間以后，Zebra 得到了另一個可達 10.0.0.0/24 的路由，這個新的路由是通過路由器 B 得到的。注重在下面的清單中，Zebra 通過 192.168.1.2 到達 10.0.0.0/24，而不是先前的路徑。
