Since the release of SFOS 19.5, BGP will not advertise routes that are not the same as an interface subnet. For example, if you are advertising 10.1.0.0/16, and your interface has IP 10.1.1.1/24, no route will be advertised.
However, there is a way to allow summarized networks. This can be done via the command line. You can connect via ssh or within the web interface by clicking on the firewall name at the right top and select “Console” in the dropdown menu.
Within the console, login with the admin account and select option “3. Route Configuration”, then select option “1. Configure Unicast Routing” and as last select option “3. Configure BGP”. Following the commands below to allow summarization:
bgp> enable
bgp# configure terminal
bgp(config)# router bgp
bgp(config-router)# no bgp network import-check
This should take effect right away. If everything is working as expected, you can save the configuration by using the “wr mem” command.
bgp(config-router)# wr mem
Configuration saved to /conf/routing/bgpd.conf
