I am trying to use a loopback interface for /24 advertised to multiple ISP’s over BGP and the break down the /24 to different vlan’s. It works fine if I use a physical interface for that /24 but not if it’s a loopback interface. the loopback interface response to ping from the fortinet of the full /24 range.
I wonder if this limitation of the loopback interface or a bug?

Hi Joele,
What happens when you do a
get router info bgp neighbors x.x.x.x advertised-routes
?
Other way you might approach this is removing the network segment from the loopback and just create on the config networks in bgp the /24 but insert this in the bgp config
set network-import-check disable
This will announce the network even if you don't have it internally in your routing table as connected for example
Regards,
Andres
