Help with network command lines

[surfing10]

Hi all,
I need to recreate the ethernet interfaces from my Dlink to the Asus AC68U router.

So what I have today is:

Fiber -> ONT -> Dlink -> PC & TV

WAN1 - PPPoE
VLAN 10 - Pri 0
Dynamic IP address
MTU 1492
NAT Enable

WAN2 - Static
VLAN 20 - Pri 3
IP Address: 10.xxx.xxx.xxx, Mask: 255.255.128.0, Gateway: 10.xxx.xxx.xxx
MTU 1500
NAT Enable
IGMP Proxy Enable

I have enable VLAN on the Asus GUI, but I can't find this information using the command line.

This is my ip link show today:

admin@RT-AC68U:/tmp/etc# ip link show
1: lo: <LOOPBACK,MULTICAST,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 40:16:7e:30:df:78 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 40:16:7e:30:df:78 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000
    link/ether 40:16:7e:30:df:7c brd ff:ff:ff:ff:ff:ff
5: vlan1@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
    link/ether 40:16:7e:30:df:78 brd ff:ff:ff:ff:ff:ff
7: vlan10@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP
    link/ether 40:16:7e:30:df:78 brd ff:ff:ff:ff:ff:ff
8: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
    link/ether 40:16:7e:30:df:78 brd ff:ff:ff:ff:ff:ff

How do I recreate that using ip link set correctly?

What is these interfaces: eth0, eth1 and eth2? Which one is LAN and WAN?
I have vlan1 and vlan10. Why?? Why not VLAN10 and VLAN 20? I did this on the LAN -> IPTV settings.

Other strange thing is the Static Route settings. I did create (in LAN -> Route) 8 static routes and I can't see them in command line. What is the correct command line to show that? With ip route show I can't see.

Thanks
