Thanks Minoru for the response. Given this feature is not available, do you
know if it is possible
to match both VLAN and MPLS tags in one flow entry? For example, the
following:
If (vlan_id ==10 and mpls_label==20): drop packet
or we will need to first let's say match on MPLS label and pop its label in
the first flow table
and then match on the vlan_id in the second table and drop the packet there
Thanks!!
