Hi, I found an issue when I try to encapsulate a packet with multiple MPLS labels (I know, for current ovs, it only support stack with depth 3.) I encapsulated a packet with MPLS three times and decapsulated them immediately. From tcpdump, the original packet may become malformed. Is it a bug or a limitation?
To help you reproduce, my testbed looks like this: h1 ---- s1 ----- h2 In s1, the rule is: cookie=0x0, duration=4.179s, table=0, n_packets=4, n_bytes=392, priority=1,ip,in_port=1 actions=push_mpls:0x8847,set_field:52->mpls_label,push_mpls:0x8847,set_field:51->mpls_label,push_mpls:0x8847,set_field:50->mpls_label,pop_mpls:0x8847,pop_mpls:0x8847,pop_mpls:0x8847,output:2 I found the issue occurs only on packets with n times encapsulations. (n >= 2, which means, push 1 tag and remove that tag directly works fine). I tired this on OVS-2.4 and OVS-2.5.90. And, I'm using ubuntu 14.04LTS. Thanks, Da
