+++ This bug was initially created as a clone of Bug #1917605 +++ Description of problem: Consider a scenario where multiple pods to be external gateways for pod such as: ovn-worker1 ovn-worker2 pod A----OVN--eth0 ----------- External GW Pod1 (172.0.0.4) | |----- External GW Pod2 (172.0.0.5) | |------ cluster default gateway (172.0.0.1) pod A now has 2 ecmp routes to 172.0.0.4, and 172.0.0.5. Now, we delete External GW Pod1. pod A should still use 172.0.0.5 as its only other ECMP gateway. Instead, we see that deleting External GW Pod1, results in a delete for the ovn_cluster_router policy for this pod A. This causes traffic from pod A to now go via the default cluster gateway (172.0.0.1) .
