Hi All, I have an issue with popping multiple mpls headers with ovs. The pushing via push_mpls works fine but the popping via pop_mpls triggers a warning in the log and the operation is not accomplished.
|WARN|system@ovs-system: execute pop_mpls(eth_type=0x8847),pop_mpls (eth_type=0x800),2 failed (Invalid argument) on packet mpls,vlan_tci=0x0000, dl_src=ba:bd:0d:9d:c5:ee,dl_dst=ea:f5:19:d4:e2:4f,mpls_label=15,mpls_tc=0,mpls_ttl=64,mpls_bos=0,mpls_lse1=45376 with metadata skb_priority(0),skb_mark(0), in_port(1) mtu 0 I'm using the last version of OVS : 2.12.90. My OpenFlow rules are the following : sudo ovs-ofctl add-flow $S1 "table=0,in_port=$S1_ETH2,eth_type=0x8847,mpls_bos=1,actions=pop_mpls:0x8847,resubmit(,0)" sudo ovs-ofctl add-flow $S1 "table=0,in_port=$S1_ETH2,eth_type=0x8847,mpls_bos=0,actions=pop_mpls:0x800,output:$S1_ETH1" Any hint how to solve this? Many thanks. Adele.
