Examples: Stacking and Rewriting Gigabit Ethernet IQ VLAN Tags

Configure a VLAN CCC tunnel in which Ethernet frames enter the tunnel at interface ge-4/0/0 and exit the tunnel at interface ge-4/2/0.

The following examples show how to perform the following tasks:

Push a TPID and VLAN ID pair on ingress.
Stack inner and outer VLAN tags.
Swap a VLAN ID on ingress.
Swap a VLAN ID on egress.
Swap a VLAN ID on both ingress and egress.
Swap the outer VLAN tag and push a new VLAN tag on ingress; pop the outer VLAN tag and swap the inner VLAN tag on egress.
Swap a VLAN ID and TPID pair for both VLAN tags on ingress and on egress.
Pop the outer VLAN tag and swap the inner VLAN tag on ingress; swap the outer VLAN tag and push a new VLAN tag on egress.
Pop two VLAN ID and TPID pairs on ingress; push two VLAN ID and TPID pairs on egress.
