ASR 903 as a switch

Hello. I'm new to ASR 903 hardware. Please, could someone explain and give simple example on how to make some interfeces act as a switchport access and some as trunk?

I need to connect two other routers through AS903, using port-channel.

Hi,You need to create sub

Hi,

You need to create sub-interfaces and use dot.1q.  Here is an example:

RP/0/RSP0/CPU0:router# show run | begin GigabitEthernet0/5/0/0
Mon Sep 21 11:15:42.654 EDT
Building configuration...
interface GigabitEthernet0/5/0/0
shutdown
!
interface GigabitEthernet0/5/0/0.0
encapsulation dot1q 100
!
interface GigabitEthernet0/5/0/1
 
here is the link:

Are ASR 903 and ASK 9K

Are ASR 903 and ASK 9K similar in concept? Reading given PDF, which is from ASR 9K documentation did not elighten me, there is no commands, used in this manual, on 903 router.

Your exapmle is about creating routed subinterface from trunk connection, to terminate 802.1q VLAN. I need different thing. I need for several ports on ASR 903 line cards to act as a SWITCH.

With exception that instead of Vlan interface, i should use BDI interface and there shouldn't be tagged traffic in the corresponding bridge-domain.
