the product is no longer active in Red Hat Bugzilla.
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 of problem:
A metallb configuration always have a deny all route rule to avoid external routers to be able to inject routes to the ocp nodes.
In some particular scenarios, we allow injecting a rule that overrides that in the final part of the configuration.
So, in the configuration we have something like
route-map 172.18.0.5-in deny 20
Then we update the configuration file appending
route-map 172.18.0.5-in permit 20
and we reload it with the frr-reload.py script.
The current-config shows the rule being updated correctly, but a refresh route message is not sent to the neighbor, so any published route is not received.
This is different from what is observed with frr 8.4.2, where as soon as we update the configuration file a route refresh message is sent out

Version-Release number of selected component (if applicable):
7.5.1
How reproducible:
Always
Steps to Reproduce:
Described above.
- A neighbor configured to push routes
- an initial config with a deny all route rule
- a new config with a permit any to amend the previous deny
Actual results:
We must either kill the session or restart the frr instance to see the routes
Expected results:
The local frr instance asks for routes to the neighbor
