Re: [ovs-discuss] MPLS issue in OVS

Hi,

 I have upgraded kernel :
 uname -a
Linux ubuntu 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017
x86_64 x86_64 x86_64 GNU/Linux


  I am seeing this weird behavior, I see traffic as expected for sometime
and then OVS start dropping all the packets. Below is the log I see:

Re: [ovs-discuss] MPLS issue in OVS

2017-04-05 Thread Justin Pettit 
I know very little about the MPLS integration, but I have one thing that might 
be worth checking.  Are you using the OVS kernel module that came with OVS 
2.6.1 or the one that comes with Linux 4.2?  Linux 4.2 came out a year before 
OVS 2.6, and 2.6 introduced MPLS TTL.  It looks like the kernel datapath is 
rejecting the attempt to add that flow, so I'd make sure that you're using the 
kernel datapath that came with the OVS release.

[ovs-discuss] MPLS issue in OVS

2017-04-04 Thread f 62 
I have configured ovs flows like this on ovs bridge:

1. cookie=0x0, duration=2261.104s, *table=0*, n_packets=23, n_bytes=1702,
idle_age=1877, tcp,in_port=8,nw_src=51.0.0.4 actions=group:1,resubmit(8,7)

2.  group_id=1,type=select,bucket=actions=set_field:fa:16:3e:48:
cd:9e->eth_dst,resubmit(,5)

3. cookie=0xb2c6f4127f2f27cc, duration=24849.587s, *table=5*,
n_packets=303, n_bytes=22830, idle_age=1940,
priority=0,ip,dl_dst=fa:16:3e:48:cd:9e
actions=push_mpls:0x8847,load:0x1ff->OXM_OF_MPLS_LABEL[],
set_mpls_ttl(255),mod_vlan_vid:3,output:2

4. cookie=0x0, duration=17142.766s, *table=7*, n_packets=36, n_bytes=2664,
idle_age=1996, priority=2,ip,dl_dst=fa:16:3e:78:13:cd
actions=push_mpls:0x8847,load:0x1fe->OXM_OF_MPLS_LABEL[],
set_mpls_ttl(254),mod_vlan_vid:3,output:2

ovs port:2 is patch port to tunnel bridge (another ovs bridge)

On tunnel bridge, this is the flow:

5. cookie=0x0, duration=2465.760s, table=22, n_packets=36, n_bytes=2664,
idle_age=267, priority=1,dl_vlan=3 actions=strip_vlan,load:0x49->
NXM_NX_TUN_ID[],output:2


*If in (3) and (4) I do not set MPLS fields, traffic works as expected.*
