Major Problem Description: Clearly explain the issue.
On IPV6, in OVN-Kubernetes on Layer2 topology, on the GR depending on whether I have at least 1 ETP=local load balancer or not, I am hitting an inconsistency in drop behaviour.
case with ETP=local nodeport service:

the priority 60 which matches on node-ip i.e the current nodeIP causes the drop.
That flow takes precedence over the src-ip route flow I have:

excluding the nodeIP and things start to work since it hits my src-ip routes
Impact Assessment: Describe the severity and impact (e.g., network down,availability of a workaround, etc.).
Software Versions: Specify the exact versions in use (e.g.,openvswitch3.1-3.1.0-147.el8fdp).
Issue Type: Indicate whether this is a new issue or a regression (if a regression, state the last known working version).
Reproducibility: Confirm if the issue can be reproduced consistently. If not, describe how often it occurs.
I can consistently reproduce it in local gateway mode (not sure if this is also impacting shared gateway..)
Reproduction Steps: Provide detailed steps or scripts to replicate the issue.
Expected Behavior: Describe what should happen under normal circumstances.
Given my pod in UDNA is trying to reach nodeport service in UDNB, and given in L2 the router has the nodeIP, I expect the drop to happen consistently but drop happens only if at least 1 etp-local load balancer is present. Why is that?
Observed Behavior: Explain what actually happens.
Troubleshooting Actions: Outline the steps taken to diagnose or resolve the issue so far.
