Symptoms

When upgrading from v10.2.4 to v11.5.x or v11.6.x, with fallback set to null in a wideip pool, the new pool will have fallback-ipv4 set to any6.

Impact

The fallback-ipv4 is incorrectly set to an IPv6 address rather than an IPv4 address.

Conditions

-- Upgrading from v10.2.4 to v11.5.x or v11.6.x. -- Fallback set to null in a wideip pool.

Workaround

The only workaround is to set Fallback to a different value before upgrading, and then set back after upgrade is complete.

Fix Information

None
