Bug #16122
open
Interfaces=>Vlans, ipsecX interfaces are listed in the VLAN parent interface config dropdown menu.
Added by Lev Prokofev about 1 year ago.
Updated about 1 month ago.
Description
If the system has configured IPsec VTI, the "ipsecX" interface is listed in the dropdown menu of the VLAN parent interface config, which is not correct.
Tested on 25.07.a.20250313.1703, 25.03.b.20250306.0140, and 24.11 release.
