Hi Fabio, You need to use bridge domains and evc style configuration on the asr1000s for l2 forwarding. BDI interfaces can serve for l3 , like a bvi on ios
So you need something like this for l2 forwarding interface GigabitEthernet0/0/0 service instance 1 ethernet encapsulation dot1q 1 bridge-domain 1 interface GigabitEthernet0/0/1 service instance 1 ethernet encapsulation dot1q 1 bridge-domain 1 Brian > -----Original Message----- > From: cisco-nsp [mailto:[email protected]] On Behalf Of > Fabio Mendes > Sent: giovedì 24 settembre 2015 17:42 > To: [email protected] > Subject: [c-nsp] ASR 1002X and SPA-10X1GE-V2 > > Hi, > > A couple of months ago we bought a couple of ASR-1002Xs with 10X1GE-V2 > cards on each one.
