my network

Can anyone help me how to make auto failover with multihoming WAN? My scenario: WAN 1 as my primary link  and WAN 2 as secondary or backup for redundancy.

@syafrilmp hi,
you can configure static route on AR2200 and bind the BFD to detect the connection of the link.
Then enable the BGP peer with the destination address of the static route as the peer-ip.
So that, when the link faild, the static route will be removed from the routing-table, and the corresponding BGP peer turns down.

Issue Description

Customer request to add two ISP Connection as a Primary and secondary connection on one router AR2200
Solution

For Solution your Required Scenario, as primary link for ISP2 and Standby link for ISP1 , you can find below Scenario configuration for the same :
 
Example :
Multihoming WAN redundancy in Huawei AR2200-3135626-1

 
Configure connectivity at the network layer.
# Assign an IP address to each interface. Use RouterA as an example.
<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   “Enter the IP address for each interface connected to ISP”
[RouterA-GigabitEthernet1/0/0] quit
[RouterA] interface gigabitethernet2/0/0
[RouterA-GigabitEthernet2/0/0] ip address 10.1.3.1 255.255.255.0    “Enter the IP address for each interface connected to ISP”
[RouterA-GigabitEthernet2/0/0] quit
 
2- # On RouterA, configure Default routes to ISPs interfaces and Bind with NQA
[RouterA] ip route-static 0.0.0.0 0.0.0.0 X.X.X.X“NEW ISP IP address on the router” preference 80 track nqa user test
[RouterA] ip route-static 0.0.0.0 0.0.0.0 X.X.X.X“Old ISP IP address on the router” preference 60
 
3- Configure an NQA test instance on RouterA.
# Configure the ICMP NQA test instance on RouterA.
[RouterA] nqa test-instance user test
[RouterA-nqa-user-test] test-type icmp
[RouterA-nqa-user-test] destination-address ipv4  Y.Y.Y.Y “ the IP address of New ISP which is assigned at ISP Router side”
[RouterA-nqa-user-test] frequency 11
[RouterA-nqa-user-test] probe-count 2
[RouterA-nqa-user-test] start now
[RouterA-nqa-user-test] quit

Sure, let's take your topology as an example.

ip route-static 2.2.2.2 32 10.3.30.2 // suppose that the ip address of loopback interface on the left Cisco router is 2.2.2.2/32
bfd test bind peer-ip 2.2.2.2 interface g0/0/1 one-arm-echo // suppose the interface of ip 10.3.30.1 is g0/0/1
bgp 100
peer 2.2.2.2 as 100
peer 2.2.2.2 conn loo1 // suppose the source interface used to establish the bgp peer is loopback 1.
