Hi, i executed these commands in a ovswitch 2.13.0 :

sudo ovs-ofctl -O OpenFlow13 add-flow $S3 "table=1,in_port=$S3_ETH2,eth_type=0x8847,mpls_bos=0,actions=pop_mpls:0x8847,resubmit(,1)"
sudo ovs-ofctl -O OpenFlow13 add-flow $S3 "table=1,in_port=$S3_ETH2,eth_type=0x8847,mpls_bos=1,actions=pop_mpls:0x800,output:$S3_ETH1

 

but when there are 2 MPLS labels in one packet, the switch can’t pop the 2 labels and it doesn’t forward the packet, why?

If there is only one label, it works correctly.

Thanks for your attention.

Best regards
