Description
This article describes how to entirely configure SD-WAN from CLI.
Solution
To configure SD-WAN in the CLI.
Configure the WAN1 and WAN2 interfaces.
# config system interface
edit "wan1"
set alias to_ISP1
set mode dhcp
set distance 10
next
edit "wan2"
set alias to_ISP2
set ip 10.100.20.1 255.255.255.0
next
end
Enable SD-WAN and add the interfaces as members.
# config system virtual-wan-link
set status enable
# config members
edit 1
set interface "wan1"
next
edit 2
set interface "wan2"
set gateway 10.100.20.2
next
end
end
Create a static route for SD-WAN.
# config router static
edit 1
set virtual-wan-link enable
next
end
Select the implicit SD-WAN algorithm.
# config system virtual-wan-link
set load-balance-mode {source-ip-based | weight-based | source-dest-ip-based | measured-volume-based}
end
Create a firewall policy for SD-WAN.
# config firewall policy
edit <policy_id>
set name <policy_name>
set srcintf internal
set dstintf virtual-wan-link
set srcaddr all
set dstaddr all
set action accept
set schedule always
set service ALL
set utm-status enable
set ssl-ssh-profile <profile_name>
set av-profile <profile_name>
set webfilter-profile <profile_name>
set dnsfilter-profile <profile_name>
set application-list <app_list>
set logtraffic all
set nat enable
set status enable
next
end
Configure a performance SLA.
# config system virtual-wan-link
# config health-check
edit "server"
set server "208.91.112.53"
set update-static-route enable
set members 1 2
next
end
end
Results.
To view the routing table in the CLI.
# get router info routing-table all
Routing table for VRF=0
Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP
O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default
S* 0.0.0.0/0 [1/0] via 172.16.20.2, wan1
[1/0] via 10.100.20.2, wan2
C 10.100.20.0/24 is directly connected, wan2
C 172.16.20.2/24 is directly connected, wan1
C 192.168.0.0/24 is directly connected, internal
To diagnose the Performance SLA status.
# diagnose sys virtual-wan-link health-check
Health Check(server):
Seq(1): state(alive), packet-loss(0.000%) latency(15.247), jitter(5.231) sla_map=0x0
Seq(2): state(alive), packet-loss(0.000%) latency(13.621), jitter(6.905) sla_map=0x0
