Thanks Minoru for helping me. I'd appreciate it.
It seems that the ethernet type field for VLAN and MPLS are different:
VLAN: Ethertype 0x8100 and 0x88a8 should be used.
MPLS: Ethertype 0x8847 and 0x8848 should be used.
Did you also try to create packets matching the flow entry you installed
and check
if they match? if so, did you push the MPLS label first and then VLAN tag
or vice
versa? The problem is my packets do not mach with the entry.
Thanks again for your help!
