To achieve high availability of the network, let's back up the routed lines

The diagram of the lab topology is as follows:

High availability of the network: routing line backup-floating static route

(device: router Quidway R2621)

The steps of the experiment:

1. Configuration of router R1

two。 Configuration of router R2

3. Ospf configuration of router R1 R2

4. Test

1. Configuration of router R1

[Router] sysname r1

[r1] int s0

[r1-Serial0] ip add 192.168.3.1 24

[r1-Serial0] int s1

[r1-Serial1] ip add 192.168.4.1 24

[r1-Serial1] int e0

[r1-Ethernet0] ip add 192.168.1.254 24

[r1-Ethernet0] qu

[r1] ip route 192.168.2.0 24 192.168.4.2

two。 Configuration of router R2

[Router] sysname r2

[r2] int s0

[r2-Serial0] ip add 192.168.3.2 24

[r2-Serial0] int s1

[r2-Serial1] ip add 192.168.4.2 24

[r2-Serial1] int e0

[r2-Ethernet0] ip add 192.168.2.254 24

[r2-Ethernet0] loopback

[r2-Ethernet0] qu

[r2] ip rout 192.168.1.0 24 192.168.4.1

3. Configure ospf

3.1 on the R1 router

[r1] int s0

[r1-Serial0] ospf enable area 1

[r1-Serial0] standby int ser 1

[r1-Serial0] int e0

[r1-Ethernet0] ospf enable area 1

[r1-Ethernet0] qu

[r1] ospf enable

3.2 on R2 router

[r2] int s0

[r2-Serial0] ospf en area 1

[r2-Serial0] standby int serial 1

[r2-Serial0] int e0

[r2-Ethernet0] ospf ena area 1

[r2-Ethernet0] qu

[r2] ospf enable

4. Test

From the lan1 intranet, a host (192.168.1.100) ping LAN lan2 gateway (192.168.2.254bin24)

/ / during normal communication, the routing table on router R1 is shown in figure 4-1, and then the port S0 of R1 is down off. The host on lan1 appears as follows (figure 4-2), and the routing table on router R1 is shown in figure 4-3.

Figure 4-1

Figure 4-2

Figure 4-3

/ / enable port S0 on router R1. The routing table of R1 is shown in figure 4-4. The communication status of Lan1 client is shown in figure 4-5. Because of the ospf learning process between routers, customers will lose some packets.
