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