What would solve this problem?

You are implementing Q-in-Q tunneling on an EX Series switch. You want the tunnel to support all
C-VLANs; however, only some VLANs are able to send traffic across the tunnel. Switch-1 has the

[edit vlans]
user@Switch-1# show
v100 {
vlan-id 100;
interface {
ge-0/0/0.10;
ge-0/0/1.20;
}
dot1q-tunneling {
customer-vlans [ ];
}
}

    The D is correct.

    Many-to-one bundling is used to specify which C-VLANs are mapped to an S-VLAN. Many-to-one bundling is configured using the “customer-vlans” option.

    Many-to-one bundling is used when you want a subset of the C-VLANs on the access switch to be part of the S-VLAN. When using many-to-one bundling, untagged and priority tagged packets can be mapped to the S-VLAN when the “native” option is specified along with the “customer-vlans” option.
