Google should have config examples and specifics for that router type. Depending on your goals you may need to combine both to make your solution work.

I see two options:

  * Layer 2 Local Switching, which is the easiest option. You're just
    x-connecting two ports on the same switch. It's like running a patch
    cord between them.

  * Use a BDI to stitch them. Use "encapsulation default" and put both
    ports in the same BD. No need to define each VLAN ID = 802.1Q
    trunking on the ASR920.
