Doc Type: Bug Fix
Doc Text:
This update fixes a bug that prevented load-balancing of traffic on some Load-balancing service (octavia) pool members on IPv6 networks in an ML2/OVN environment. + Before this update, if you added a second `listener+pool+member` to a pool, the pool entered an ERROR state and traffic within that pool was not load-balanced. + With this update, traffic is load-balanced to all members as expected.

Description Fernando Royo 2024-02-09 17:05:09 UTC 
+++ This bug was initially created as a clone of Bug #2263550 +++

Description of problem:
When an LB IPv6 is created using a bulk command or when multiple listener-pool-member are added sequentially, the second listener-pool managed fails when adding a member, resulting in the pool's state being in an ERROR state.

The error in traceback is:

2024-02-07 12:40:56.166 13 ERROR networking_ovn.octavia.ovn_driver Traceback (most recent call last):

So apparently, the LB_VIP is enclosed in additional brackets [ ] when adding the member to the second listener-pool-member.


Version-Release number of selected component (if applicable):
RHOSP 16.2

How reproducible:


Steps to Reproduce:
1. Create a LB over a IPv6 with more than a listener-pool-member
2.
3.

Actual results:
Second pool keeps in ERROR state

Expected results:
LB created correctly
