I am following this guide
https://wiki.openwrt.org/doc/howto/mwan3

And i got stuck at the section where im supposed to
"Verify the Routing Tables"

My setup is Asus RT-N16 running OpenWrt Chaos Calmer 15.05.1 / LuCI 15.05-188-g87e9837 Release (git-16.043.44305-e2f9172)

AT&T Gigapower (using DHCP) on WAN PORT
and
COMCAST (using DHCP) on PORT 4

I got stuck at this part of the guide

Verify the routing table

If configured correctly, you should have a default gateway (the lines with a target address of 0.0.0.0/0) with a unique metric set for each WAN interface. For example:

default via 10.0.3.2 dev eth1  proto static  src 10.0.3.15  metric 10
default via 10.0.4.2 dev eth2  proto static  src 10.0.4.15  metric 20
:!: IMPORTANT:  :!: Ensure that every WAN interface has a gateway IP and metric defined

Author looks like hes putting Class A IPs for the routing but doesnt mention the point of each one.

My router the RT-N16 is gateway 192.168.0.1
all my computers are on 192.168.0.X

Connected to my router on WAN1 is my ATT modem @ which is 192.168.1.254

Connected to port 4 on my router is COMAST modem

Im sure i can figure it out but i just dont understand the information it wants

Any help is appreciated..
Thanks in Advance

in terminal just type "ip route" and that should display your current routing table

or

via Luci (assuming you installed luci-app-mwan3 which is more convenient to mess with rather than using the terminal)
go to Network >> Load Balancing
then click Advance Tab
and then click Diagnostic Tab
select the interface you had and click check routing table

The discussion might have continued from here.
