Flow redirect with ECMP

Jarek — Mon, 22 May 2017 21:59:00 GMT

Hi,

I have checked the doc. and so on... but didn't find answer to my question.

Is it possible to do ECMP with flow-redirect ?

Example

I have config like bellow:
- 2 default gatways with the same metric
configure iproute add default 1.1.1.1 100
configure iproute add default 2.2.2.2 100

- I have enabled iproute sharing

The traffic is equally send through 2 GW's.

I use also flow-redirect with prio 150 to send traffic from 10.0.0.0/24 via 192.168.1.1

And that is working fine.

My goal is:

I want to add a second flow-redirect with prio 150 to send traffic from 10.0.0.0/24 via 192.168.1.3

and have ECMP from 10.0.0.0/24 via192.168.1.1 and 192.168.1.3

Is it possible to achieve this ?

Hi Jarek,

No, this is not currently supported in EXOS. Flow-redirect only allows one next-hop per priority value.

Thank you for answer Brandon.

Are there any chance to add this feature to 15.X or 16.X branch?
