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:
Swap a TPID and VLAN ID Pair for Both VLAN Tags on Ingress and on Egress
Pop a TPID and VLAN ID Pair on Ingress; Push a VLAN ID and TPID Pair on Egress
Pop an Outer VLAN Tag to Connect an Untagged VPLS Interface to Tagged VPLS Interfaces
Push a TPID and VLAN ID Pair on Ingress
