Symptoms
Loading a SCF after modifying self IP may cause route in Linux kernel to be dropped. Linux host applications may not be able to connect when they are expected to.
Impact
Linux kernel default gateway route is dropped and host applications looking for the route may not be able to connect.
Conditions
Create a config with a self IP on a VLAN and a default gateway route on that VLAN, save a SCF file, then modify the self IP in that SCF file and then load the SCF.
Workaround
Reset the config to default before loading modified SCF: 1. tmsh load sys default. 2. tmsh load sys scf SCF_flename. For more information, see SOL14572: Routes configured in a single configuration file may be missing from the Linux kernel route table after loading the single configuration file, available here: http://support.f5.com/kb/en-us/solutions/public/14000/500/sol14572.
