I have an ASR9001 running 5.1.3. is it possible to configure an interface using "encapsulation ambiguous dot1q any second any" , and have DHCP requests forwarded to a DHCP server.
I have a need where I have a large number of DHCP clients that do not need to be authenticated/accounted etc, but are delivered on random QinQ combinations. I would like to treat these clients as straight dhcp clients vs. BNG (i.e. licensed) clients.
interface Bundle-Ether203.1 vrf voice ipv4 point-to-point ipv4 unnumbered Loopback203 encapsulation ambiguous dot1q any second-dot1q any
I can see the DHCP request coming in, however the debug dhcp proxy says that the discovery packets are being dropped.

Any help would be appreciated. If i have to use a BNG license for each of these clients, my 32K sessions will be effectively halved..
