Symptom
CLI "default ip routing protocol purge interface" was handled as "no ip routing protocol purge interface".
It will bring two issues in the system:
1) When you run CLI "default ip routing protocol purge interface", "no ip routing protocol purge interface" will be
generated in the running configuration
2) After you configured "no ip routing protocol purge interface", you can't revert it back to default by running
"default ip routing protocol purge interface"
Conditions
Running "default ip routing protocol purge interface" to put that CLI to default state.
Workaround
Run "ip routing protocol purge interface" to set that CLI to default state.
