Hello community, I found a situation that O couldn't comprehend 100%.
I have a SPA FG thats learning the FortiSASE users Subent (100.65.x.x) and my SPA FG has another iBGP peering (also a RR client) and for some reason the subnet is not advertised to that Fortigate. I had to configure a static route (100.65.x.x via IPSEC-SASE) and then one the network section, set the subnet to be advertised.
What am I missing here? Wouldn't BGP advertise this subnet in this case as both SASE POPS and my other FG are RR clients?
