[ovs-discuss] Packet drop when output to multiple VXLAN tunnel

[f 62]

Hi ,

    OVS is dropping packet when packet is output to multiple VXLAN tunnel.
I see following error:

These are 2 flows which classifies packet:

cookie=0x0, duration=91.547s, table=5, n_packets=4, n_bytes=296,
idle_age=63, priority=0,ip,dl_dst=fa:16:3e:db:81:44
actions=push_mpls:0x8847,load:0x1ff->OXM_OF_MPLS_LABEL[],set_mpls_ttl(255),mod_vlan_vid:3,output:2,resubmit(8,7)

cookie=0x0, duration=72.231s, table=7, n_packets=4, n_bytes=296,
idle_age=60, in_port=8
actions=strip_vlan,pop_mpls:0x0800,move:NXM_NX_REG0[]->NXM_OF_ETH_DST[0..31],move:NXM_NX_REG1[0..9]->NXM_OF_ETH_DST[32..41],push_mpls:0x8847,load:0x1fe->OXM_OF_MPLS_LABEL[],set_mpls_ttl(254),mod_vlan_vid:3,output:2


However, when output to single tunnel, traffic is fine.
