Symptoms

When a link local address is configured as a default gateway there is an error when running the 'tmsh load sys config' command: Syntax Error:(/config/bigip.conf at line: 1017) "default" unknown property. /config/bigip.config is incorrectly written with an empty interface value: cat bigip.conf|grep 'net route' -A4 net route /Common/External_default_GW { gw 169.254.200.1 interface network default }

Impact

The default gateway works, but bigip.conf may not be loaded via tmsh with the command 'load sys config'.

Conditions

-- config.allow.rfc3927 database key set to enable. -- Link local address is configured as a default gateway, as shown in the following example: cat bigip.conf|grep 'net route' -A4 net route /Common/External_default_GW { gw 169.254.200.1 interface <== This is the error network default }

Workaround

Modify the bigip.conf file, adding the correct interface, as shown in the following example, which uses 'interface Ext': cat bigip.conf|grep 'net route' -A4 net route /Common/External_default_GW { gw 169.254.200.1 interface Ext network default }
