Networking Requirements

As shown in Figure 8-3, the link RouterA->RouterB->RouterD is the primary link, and the link RouterA->RouterC->RouterD is the backup link. It is required to monitor the primary link status. If the primary link fails, the backup link starts to transmit services to reduce the impact on services. When the primary link is recovered, the primary link takes over services again.

Figure 8-3 LSDP network diagram

Configuration Roadmap

The configuration roadmap is as follows:

Configure interface IP addresses and static routes for primary and backup links to implement connectivity at the network layer.
Configure LSDP on RouterA to detect primary link connectivity in real time.

Procedure

Configure connectivity at the network layer.

Configure interface IP addresses for RouterA according to the network diagram.

<Huawei> system-view
[Huawei] sysname RouterA
[RouterA] interface gigabitethernet1/0/0
[RouterA-GigabitEthernet1/0/0] ip address 10.1.2.1 255.255.255.0
[RouterA-GigabitEthernet1/0/0] quit
[RouterA] interface gigabitethernet2/0/0
[RouterA-GigabitEthernet2/0/0] ip address 10.1.3.1 255.255.255.0
[RouterA-GigabitEthernet2/0/0] quit

On RouterA, configure static routes to 10.1.4.0/24 and 10.1.5.0/24 of RouterD.

[RouterA] ip route-static 10.1.4.0 255.255.255.0 10.1.2.2 preference 40
[RouterA] ip route-static 10.1.5.0 255.255.255.0 10.1.3.2 preference 80

Configure LSDP on RouterA.

[RouterA] interface gigabitethernet1/0/0
[RouterA-GigabitEthernet1/0/0] lsdp 10.1.4.2 10.1.2.2
[RouterA-GigabitEthernet1/0/0] quit

Verify the configuration.
