interface. If the VLAN tags associated with an outbound logical interface do not match
the normalizing VLAN identifier configured for the VLAN or VPLS routing instance, the
VLAN tags are rewritten as described in
The tables below show how VLAN tags are applied for traffic sent to and from the VLAN,
depending on how the
vlan-id
on how identifiers are configured for the logical interfaces in a VLAN or VPLS routing
instance. Depending on your configuration, the following rewrite operations are performed
on VLAN tags:
pop —Remove a VLAN tag from the top of the VLAN tag stack.
—Remove both the outer and inner VLAN tags of the frame.
pop-pop
pop-swap —Remove the outer VLAN tag of the frame and replace the inner VLAN tag
of the frame.
—Replace the VLAN tag of the frame.
swap
push —Add a new VLAN tag to the top of the VLAN stack.
—Push two VLAN tags in front of the frame.
push-push
swap-push —Replace the VLAN tag of the frame and add a new VLAN tag to the top
of the VLAN stack.
—Replace both the outer and inner VLAN tags of the frame.
