Hello everyone,
W have a network packet set consisting of custom L2 and standard L3 packets. We
want to forward these packets over VPP. When I tried to send custom L2 packet
which has a non-standard ethernet type, it had been dropped in VPP.

If we use bridge-domain, we can mask all packets and transmit them. However in
bridge-domain, it is just looking at the L2 header of all packets and
forwarding them. But we want IP packets to be forwarded to the IP nodes to take
advantages of features like fragmentation, checksum control etc.
Is there a solution to forward masked IP packets to ip-node or an alternative
way to solve the problem?
