Flow redirect with ECMP

    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?
