Hi Numan,

I assume that this implementation as a whole will not affect the stateless
use case in which the logical_router has multiple DGPs for different
ovn-chassis (chassisresident port), and with a stateless NAT rule so that
the traffic is decentralized via ECMP, right?

I mean, if I have a dgw_port peer for each chassis and configure a
stateless NAT on the router, I will continue creating the static DNAT and
SNAT path regardless of the port/chassis that the traffic passes through,
right? otherwise, this will make it impossible to balance traffic across
different chassis for the same logical_router.

Kind regards,
Roberto
