Hello Pro's

I want to deploy the same concept as switchport trunk vlan allowed 53 , 71 on an ASR 9000 trunk link.

I couldnt find a thing pointing straight to the matter, but from what I read here and there, should I create subinterfaces for each vlan tag and use dot1q 53 and dot1q 71 under the subif respectively?

i know not many people had XP with ASR9K, but any kind of help would be much  apprciated.

Thank,

Soroush.
