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 Federico Paolinelli 2022-11-08 16:33:08 UTC 
Description of problem:
Specifying a routing rule of the format 

route-rules:
  config:
    - route-table: 255
      priority: 32765

just to change the priority of a given table will fail because ip-from / ip-to are required. This is also true with the upcoming fwmark support added in https://github.com/nmstate/nmstate/pull/2072/files#diff-d7182597b1754d6ae01448ba3a7eee4f964824e7d1bfb0141e2063deac26eddfR254

A workaround is to use ip-from: 0.0.0.0/0 , but it'd be cleaner to avoid
the required field.

Upstream documentation added for the new options.
Comment 6 Fernando F. Mancera 2022-12-01 08:49:59 UTC 
When managing routing policies a good use case is to change the priority of a given table. In order to do that, nmstate must support `from all to all` route rules. When not specifying ip-from and ip-to parameters kernel considers that the rule will match everything.

In Nmstate is must to also introduce the ip family because we need to identify if it is a ipv4 or ipv6 route rule.

```
route-rules:
  config:
    - route-table: 200
      priority: 100
      family: ipv4
```

When configuring the state defined above, the user should be able to see

```
100:	from all lookup 200
```

when running  `ip rule`
