Help me to understand VLAN trunk

Hello I’m studying the manual how to work with vlans and I’m a little confused.
This is my goal:

I want to achieve is to extend the vlan-16 and vlan-15 from CCR1036 until CISCO router customer.

I’m trying this approach:
CCR1036

  • use ether1 to define VLAN15 and VLAN16
  • use ether7 of CCR1036 some as trunk

CRS125

  • use ether10 of CRS125 some as trunk

SXT-Bridge (with bridge-wireless and ports added: ether1 and wlan1)

SXT-StationBridge (with bridge-wireless and ports added: ether1 and wlan1)

CISCO Customer has defined VLAN15 and VLAN16 on his ether1

some advice on my way?
