Hi Piotr,
The configuration would be something like:
root@mx# show | compare
[edit routing-options]
+ forwarding-table {
+ export pplb;
+ }
[edit]
+ policy-options {
+ policy-statement pplb {
+ then {
+ load-balance per-packet;
+ }
+ }
+ }

Piotr,
As far as i can understand this is unrelated to contrail.
The EX9200 needs to be configured to do load balancing. If i recall correctly,
this configuration is performed in the master routing instance.
i.e.
"set forwarding-options load-balance per-packet”
should be what you are looking for.

Hi
I'm trying to do load balancing for service instances. Those instances will be
accessed externally so this traffic will be delivered via gateway.
My setup is based on configuration dedicated for MX gateway covered in
document :
http://www.opencontrail.org/how-to-setup-opencontrail-gateway-juniper-mx-cisco-asr-and-software-gw/
My setup consists of Gateway EX9200 with Junos 14.2R3.8 and Contrail 2.20
(build 64)
I'm seeing multiple paths announced by controllers. However there is no
performed ECMP like for other paths from OSPF/BGP.

Unfortunately Still I can see only one path in forwarding table.
>show route forwarding-table table VRF-6-public matching
>10.11.12.251/32<http://10.11.12.251/32>
Routing table: VRF-6-public.inet
Internet:
Destination Type RtRef Next hop Type Index NhRef Netif
10.11.12.251/32<http://10.11.12.251/32> user 0 indr
1048674 5
Push 35 1180 2
gr-0/3/0.32772
Also I've tried add additional following configuration but there is no change
in behaviour
set routing-instances VRF-6-public forwarding-options load-balance
indexed-load-balance
set routing-instances VRF-6-public forwarding-options load-balance per-flow
hash-seed
set routing-instances VRF-6-public forwarding-options
load-balance-label-capability
Does anyone has working example of ECMP on a gateway level for IP inside
Contrail VN ?
