[Yahoo-eng-team] [Bug 2052628] [NEW] [stable-only][ovn-octavia-provider] Multiple listener-pool-member on IPv6 LB getting second pool in ERROR

[Fernando Royo]

Public bug reported:

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:

netaddr.core.AddrFormatError: invalid IPNetwork [fd2e:6f44:5dd8:c956::1a]

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

This issue is only occurring in stable branches.
