I am matching and popping an mpls label, but when I output it to a port it never shows up on the other side. Here is the flow rule
cookie=0x0, duration=1121.523s, table=0, n_packets=20, n_bytes=2360, idle_age=675, priority=500,mpls,in_port=3,mpls_label=100 actions=pop_mpls:0x0800,output:1 As you can see it is matching and should output to port 1 # tcpdump -i eth3 -n tcpdump: WARNING: eth3: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth3, link-type EN10MB (Ethernet), capture size 65535 bytes 19:39:19.392924 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 57614, seq 0, length 80 19:39:21.412721 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 57614, seq 1, length 80 19:39:23.432530 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 57614, seq 2, length 80 root@SW1:/home/tepkes# tcpdump -i eth1 -n tcpdump: WARNING: eth1: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes I get no packets output. Now if I change the rule to not pop but to just output I'll see it on port 1. # tcpdump -i eth1 -n tcpdump: WARNING: eth1: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 19:43:09.537645 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 8462, seq 0, length 80 19:43:11.557091 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 8462, seq 1, length 80 19:43:13.576987 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 8462, seq 2, length 80 19:43:15.596873 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 8462, seq 3, length 80 19:43:17.616679 MPLS (label 100, exp 0, [S], ttl 255) IP 10.4.4.1 > 10.1.1.1: ICMP echo request, id 8462, seq 4, length 80 I cannot find where it is dropping. The version of ovs is 2.0.1, but I did run the most recent version from git with similar results. Any help here would be appreciated. Tim
