Stacking Two VLAN Tags
On Ethernet IQ, IQ2 and IQ2-E interfaces, on MX Series router Gigabit Ethernet,
Tri-Rate Ethernet copper, and 10-Gigabit Ethernet interfaces, and on aggregated
Ethernet interfaces using Gigabit Ethernet IQ2 and IQ2-E or 10-Gigabit Ethernet PICs
on MX Series routers, to push two VLAN tags in front of tagged frames entering or
exiting the interface, include the push-push statement in the input
VLAN map or the output VLAN map:
push-push;
You can include this statement at the following hierarchy levels:
-
[edit interfaces interface-name unit logical-unit-number input-vlan-map] -
[edit interfaces interface-name unit logical-unit-number output-vlan-map] -
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number input-vlan-map] -
[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number output-vlan-map]
