This article describes that 'get router info bgp network x.x.x.x' shows the output for a prefix even if it does not match the route map.
For example, consider a static route configured in FortiGate with a tag (in this case 1122), and based on tag matching, it is necessary to filter static route redistribution into BGP.
config router static
edit 2
set dst 1.2.3.0 255.255.255.0
set gateway 10.9.15.254
set distance 254
set device "port17"
next
edit 3
set dst 4.5.6.0 255.255.255.0
set gateway 10.9.15.254
set distance 254
set device "port17"
set tag 1122
next
end
- Create a route map as below:
FGT # config router route-map
edit "match-tag"
config rule
edit 1
set match-tag 1122
next
edit 2
set action deny
next
end
next
end
- Use route-map 'match-tag' in BGP configuration
FGT # config router-bgp
config redistribute "static"
set status enable
set route-map "match-tag"
end
end
The output of 'get router info bgp network' shows a prefix (in this case 4.5.6.0) in the output since the static route for this prefix has tag 1122. It is also possible to confirm this but checking the learned routes on the remote BGP peer by using the command 'get router info bgp neighbor x.x.x.x received-routes'.

But if the output of 'get router info bgp network x.x.x.x' is checked, the output for all prefixes which are matching tags and which are not will be visible.
