ASR920 : EVC's and Untagged/Access ports?

Can someone sanity check the below if possible. I simply want several interfaces on an ASR920 to be part of the same VLAN. The ports however are connecting to host devices so need to be untagged ports:

 

ethernet evc VLAN101
!
interface GigabitEthernet0/0/2
 no ip address
 service instance 1 ethernet VLAN101
  encapsulation untagged
  bridge-domain 101
 !
!
interface GigabitEthernet0/0/3
 no ip address
 service instance 1 ethernet VLAN101
  encapsulation untagged
  bridge-domain 101
 !
interface BDI101
 ip address 10.0.0.254 255.255.255.0

It works fine but I don't know if it's the correct method of doing this using EVC's? Should I instead have 'encapsulation default'? Or is there another method I shoudl be using instead?


Thanks

I removed my comment (sorry I mixed the question with another)

This is on an ASR920 so it's not done the same. 'Switchport' isn't even an option on the ports as the ASR920 is a router.

 

You have to use EVC's. I just need to clarify the correct method of using EVC's for untagged ports.

Hi

this config looks fine to me, but

have you attempted STP (Spanning tree) integration?

ASR920 only supports MST, backwards compatible with Rapid-PVST+

This is somthing I am struggling with (CDP seems to work) between the ASR920 and ME3600 I am running but not STP, any pointers?
