Routin
Task configuration of 1.staticrouter01
Networking requirements
The IP addresses and masks of the interfaces and hosts of the switch are shown in figure 1-2. Static routing is required so that between any two hosts in the figure
Can communicate with each other.
Configuration step
(1) configure the IP address of each interface (abbreviated)
(2) configure static rout
# configure the default route on Switch A.
System-view
[SwitchA] ip route-static 0.0.0.0 0.0.0.0 1.1.4.2
# configure two static routes on Switch B.
System-view
[SwitchB] ip route-static 1.1.2.0 255.255.255.0 1.1.4.1
[SwitchB] ip route-static 1.1.3.0 255.255.255.0 1.1.5.6
# configure the default route on Switch C.
System-view
[SwitchC] ip route-static 0.0.0.0 0.0.0.0 1.1.5.5
(3) configure the host
The default gateway for configuring Host An is 1.1.2.3. The default gateway for host B is 1.1.6.1. The default gateway for host C is 1.1.3.1.
The specific configuration process is brief.
Check the ip address of hostA and test it
Task configuration of 2.staticrouter02
Networking requirements
Configure a static route on Switch A to reach the 120.1.1.0 Universe 24 network segment, and configure a static route on Switch B to reach
Up to 121.1.1.0 amp 24 network segments, and all enable BFD detection function.
Configure a static route on Switch C to reach the 120.1.1.0 Universe 24 network segment and the 121.1.1.0 Universe 24 network segment.
When the link that Switch An and Switch B communicate through L2 Switch fails, BFD can quickly sense and cut
Switch to Switch C for communication.

Switch B Vlan-int10 12.1.1.2/24 Vlan-int13 13.1.1.1/24
Switch C Vlan-int11 10.1.1.100/24 Vlan-int13 13.1.1.2/24
Configuration step
(1) configure the IP address of each interface (abbreviated)
(2) configure static routing and BFD
# configure static routes on Switch An and enable BFD detection, using two-way detection.

Do a test first to see if you can communicate with ping
Before disconnecting the main switch, test the use of switch C to see if you can ping
