Huawei static routing Dynamic routing configuration

First, configure the device name and IP address:
R1:
Enter system view, return user view with Ctrl + Z.
[Huawei]sysname R1
[R1]interface G0/0/1
[R1-gigabitethernet0/0/1]ip address 202.100.1.1 255.255.255.0
Quit
[R1]interface G0/0/2
[R1-gigabitethernet0/0/2]ip Add 202.100.2.1 255.255.255.0
Quit
[r1-gigabitethernet0/0/1]int Lo 0 ===== Create loopback interface
[R1-loopback0]ip Add 1.1.1.1 255.255.255.255
[R1-loopback0]quit

R2:
[R2]interface G0/0/1
[R2-gigabitethernet0/0/1]ip Add 202.100.1.2 255.255.255.0
[R2-gigabitethernet0/0/1]int g0/0/0
[R2-gigabitethernet0/0/0]ip Add 202.100.3.2 255.255.255.0
[R2-gigabitethernet0/0/0]int Lo 0
[R2-loopback0]ip ad 2.2.2.2 255.255.255.255
[R2-loopback0]quit

R3
[R3]int G0/0/2
[R3-gigabitethernet0/0/2]ip Add 202.100.2.3 255.255.255.0
[R3-gigabitethernet0/0/2]int g0/0/0
[R3-gigabitethernet0/0/0]ip Add 202.100.3.3 255.255.255.0
[R3-gigabitethernet0/0/0]int Lo 0
[R3-loopback0]ip Add 3.3.3.3 255.255.255.255

Test
<r1>ping-c 2 202.100.1.2 =====ping two packets
<r1>display IP routing-table = = = View routing table

Two, configure static routes
[R1]ip route-static 3.3.3.3 255.255.255.255 202.100.2.3 = = = Add static Routes
[R1]ip route-static 202.100.3.0 255.255.255.0 202.100.2.3
[r1]display IP routing-table =====static stands for static route, 60 represents static route priority

Three, configure a floating route for backup
To configure a backup static route, which can go R2 when a link between R1 and R3 fails.
[R2]ip route-static 3.3.3.3 255.255.255.255 202.100.3.3
[r1]ip route-static 202.100.3.0 24 202.100.1.2 Preference
[R1]ip route-static 3.3.3.3 202.100.1.2 preference
[R3]ip route-static 202.100.1.0 255.255.255 .0 202.100.3.2
[r1]tracert 202.100.3.3
[r1]interface G0/0/2
[R1-gigabitethernet0/0/2]undo shutdown ( Note: The No drop configuration command in Huawei devices undo) Here restart can also
[R2]ip route-static 0.0.0.0 0.0.0.0 202.100.3.3 = = Add default route
[R2]ping 202.100. 2.1
Four, configure the default route
to configure a backup default route, R1 when a link between R2 and R3 fails.
[R2]ip route-static 0.0.0.0 0.0.0.0 202.100.1.1 preference
[r3]ip route-static 0.0.0.0 0.0.0.0 202.100.2.1 pref Erence
[R2]int g0/0/0
[R2-gigabitethernet0/0/0]shut
[r2-gigabitethernet0/0/0]

[R2]tracert 202.100.2.3
Traceroute to 202.100.2.3 (202.100.2.3), Max hops:30, packet length:40,press Ctrl_c-break
