<------------------
There is a cosmetic bug in Junos that makes Route Label be offset 4 bits to the
left. So displayed label = int (vni / 16).
I am running 3.0.2.1-4 but I was discussing yesterday with the expert and he
didn’t mention any recent fix...
Cheers,
Ato

Hi Ato,
yes, when I convert from hex it is VNI number. However it works only in Auto
Configured Vxlan mode. Can you please try User Configured on your side, if you
have zero as well?
thanks

Hi Jakub,
Please look at the real hex value of the MPLS label. Is it zero? The decoder
considers last 4 bits as ToS, BoS, and that’s not valid for VxLAN.
Cheers,
Ato

Hi Ato,
I downloaded official 3.0.2 and it behaves same with VXLAN User Configured.
When I switched to Automatic, it starts to send appropriate VNI as Ethernet tag
id, but MPLS label is still 0. Should we see VNI tag under MPLS label in
Wireshark?
Can you send us your capture?
Thanks

Hi Jakub,
First let me clarify one thing.
I had written: “In that case I think MPLS label 0 is normal but Ethernet Tag
should be different from zero, and it is zero.”
This is wrong. MPLS label 0 is not normal. I checked with our expert and also
did some tests. In all my tests with 3.0.2, both Ethernet tag and MPLS label
are set to the same non-zero value. This is true both for floating IP and for
non-floating. So what you are seeing in the tcpdump (MPLS label 0, Ethernet tag
0...) doesn’t look normal. There may be something specific to your setup.
Would you try to create it from scratch? Please check the route in the control
node introspect (TCP port 8083) and see in the bgp.evpn.0 table what label
value the route has.
Cheers,
Ato

Antonio,
yes, we have VXLAN encapsulation priority and Indetifier Mode is User
Configured.
It is floating ip pool with VNI 64512 and Route Target 64512:64512

Hi Jakub,
I guess under “Configure > Infrastructure > Global Config > Forwarding Options
> Encapsulation Priority Order” you have VXLAN on top, right? In that case I
think MPLS label 0 is normal but Ethernet Tag should be different from zero,
and it is zero.
What is VxLAN Identifier Mode set to?
How is the VN configured? What VNI does it have?

Ato

Hi Antonio,
thanks for quick reply! I will try to do change type.
It is Contrail 3.0.2 (3 weeks old build).
Thanks a lot!

Hi Jakub,
Cisco is sending Type 5 (IP Prefix) EVPN routes that we don’t support. Do you
know if there is any way to configure IOS XR so it does generate IP/MAC (Type
2) EVPN routes instead?
As for the MPLS Label Stack set to 0 by Contrail, what version are you running?
Cheers,

does anybody tested Contrail 3.X with Cisco ASR9006 IOS XR Software, Version

We are trying to run EVPN. BGP peering is established, but there is mismatch in
BGP update messages. We are getting this from contrail controller:

I attached also captured tcpdump files with update messages from contrail to
cisco (contrail) and from cisco to contrail (cisco).
Thanks,
