RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Mingyu Shi 2023-03-16 06:42:43 UTC 
Description of problem:
Currently, apply route rules without priority, nmstate/NM set it as prioity 30000. When apply the same state twice, the prioiry will change to 30001. Repeat and it will change to 30002,30003, etc.

Version-Release number of selected component (if applicable):
nmstate-2.2.7-1.el9.x86_64
nispor-1.2.10-1.el9.x86_64
NetworkManager-1.42.2-1.el9.x86_64
DISTRO=RHEL-9.2.0-20230314.47

How reproducible:
100%

Steps to Reproduce:
cat << EOF > rules.yaml
route-rules:
  config:
    - ip-from: 8.8.8.8/24
      ip-to: 200.1.1.1/24
      route-table: 100
routes:
  config:
    - destination: 0.0.0.0/0
      next-hop-interface: veth0
      next-hop-address: 100.1.1.254
      table-id: 100
interfaces:
  - name: veth0
    type: veth
    state: up
    ipv4:
      enabled: true
      address:
        - ip: 100.1.1.1
          prefix-length: 24
    veth:
      peer: veth0_p
EOF
nmstatectl apply rules.yaml
ip rule # 30000
nmstatectl apply rules.yaml
ip rule # 30001

Actual results:
0:      from all lookup local
1000:   from all lookup [l3mdev-table]
30001:  from 8.8.8.0/24 to 200.1.1.0/24 lookup 100 proto static
32766:  from all lookup main
32767:  from all lookup default

Expected results:
Nothing changed

Additional info:
It comes from https://bugzilla.redhat.com/show_bug.cgi?id=1911397#c6, in the earlier version, nmstate won't change the priority.

        - ip: 100:1:1::1
          prefix-length: 24

If using dual stack rules, the priority will increase by 2 for every applying.
