FRR attempts to cycle IPsec VTI interfaces even when disabled/not running
If FRR is installed but disabled or otherwise not running,
frr_ipsec_reload() will still attempt to send an FRR control command which will block because FRR is not running. This can cause issues when attempting to apply IPsec settings (#10736).
At a minimum,
frr_ipsec_reload() should check if the zebra daemon is running before attempting to issue its command(s).
