Opened: May 23, 2018
Severity: 3-Major

Symptoms

Configuration tool fails to configure management-ip when default routes exist for both IPv4 and IPv6.

Impact

Cannot successfully change an IPv4 or IPv6 management-ip address using config. For either of the above cases, if the IP addresses are switched back to IPv4/IPv6, the config tools fails to configure management-ip with this error: ERROR: route_mgmt_entry count is 2

Conditions

This can happen in following two scenarios: -- A configured IPv4 management-ip that is switched to IPv6. -- A configured IPv6 management-ip that is switched to IPv4.

Workaround

Manually delete the default6 (if current management-ip is IPv4) or default (if current management-ip is IPv6) management-route by running the following command: tmsh delete sys management-route <default/default6>

Fix Information

Config tool now works to configure management-ip when default routes exist for both IPv4 and IPv6, so you can switch back and forth between IPv4 and IPv6 IP addresses without error.
