BGP Stop advertising routes out except default

[southside]

Hi All,

I have configured a Fortigate 501E with BGP peering for inside and outside interfaces (Architects design). It seems that the internet routes are being advertised out to the external router. How can I stop these routes being advertised on the outside BGP instance?

It looks fine from the GUI but when I check the outside router I can see all the internal routes.

Regards

Adrian

Why do you need BGP on the inside interface? Usually you turn on BGP on the outside interface and internal routing protocol inside (OSPF for example) or just static.
