在本文中我们将介绍通过其他命令查看路由表的序列号，以及增加的路由等。

　　如果我们使用show route failover命令，我们可以看到路由表的序列号。

　　ciscoasa(config)# show route failover

　　Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP

　　D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

　　N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

　　E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP

　　i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

　　* - candidate default, U - per-user static route, o - ODR

　　P - periodic downloaded static route

　　Gateway of last resort is 10.104.54.129 to network 0.0.0.0

　　Routing table seq num 5

　　Reconvergence timer expired

　　D 20.20.210.0 255.255.255.0 [90/28416] via 192.101.1.30, 0:13:14, outside, seq 5

　　D 20.20.249.0 255.255.255.0 [90/30976] via 192.101.1.30, 0:13:14, outside, seq 5

　　D 20.20.250.0 255.255.255.0 [90/33536] via 192.101.1.30, 0:13:14, outside, seq 5

　　O IA 172.198.40.0 255.255.255.0 [110/30] via 192.168.32.2, 0:12:37, inside, seq 5

　　O IA 172.168.34.0 255.255.255.0 [110/20] via 192.168.32.2, 0:12:37, inside, seq 5

　　O IA 172.188.36.0 255.255.255.0 [110/30] via 192.168.32.2, 0:12:37, inside, seq 5

　　O IA 172.16.30.0 255.255.255.0 [110/20] via 192.168.32.2, 0:12:40, inside, seq 5

　　C 10.104.54.0 255.255.255.0 is directly connected, mgmt, seq 4

　　C 192.101.1.0 255.255.255.0 is directly connected, outside, seq 5

　　C 192.168.253.0 255.255.255.0 is directly connected, failover, seq 0

　　C 192.168.32.0 255.255.255.0 is directly connected, inside, seq 5

　　S* 0.0.0.0 0.0.0.0 [1/0] via 10.104.54.129, mgmt, seq 5

　　如果我们使用debug route ha命令，我们将看到下面增加的路由：

　　ROUTE HA: RIB Epoch number 5 assigned to NDB: 192.168.32.0

　　ROUTE HA: Sending Message Version: 1 Action: add Object: route Address: 192.168.32.0 Mask: 255.255.255.0

　　ROUTE HA: RIB Epoch number 5 assigned to NDB: 172.16.0.0

　　ROUTE HA: Sending Message Version: 1 Action: add Object: route Address: 172.16.30.0 Mask: 255.255.255.0

　　ROUTE HA: RIB epoch number 5 assigned to SDB: 172.16.30.0

　　ROUTE HA: RIB Epoch number 5 assigned to NDB: 172.168.0.0

　　ROUTE HA: Sending Message Version: 1 Action: add Object: route Address: 172.168.34.0 Mask: 255.255.255.0

　　ROUTE HA: RIB epoch number 5 assigned to SDB: 172.168.34.0

　　ROUTE HA: RIB Epoch number 5 assigned to NDB: 172.188.0.0

　　ROUTE HA: Sending Message Version: 1 Action: add Object: route Address: 172.188.36.0 Mask: 255.255.255.0

　　ROUTE HA: RIB epoch number 5 assigned to SDB: 172.188.36.0

　　ROUTE HA: RIB Epoch number 5 assigned to NDB: 172.198.0.0

　　ROUTE HA: Sending Message Version: 1 Action: add Object: route Address: 172.198.40.0 Mask: 255.255.255.0

　　ROUTE HA: RIB epoch number 5 assigned to SDB: 172.198.40.0

　　该功能在ASA上早已开启，所以你只需要在ASA上设置冗余和路由就可以了。
