Get dynamic routing info:

# BGP
get router info bgp network
get router info bgp summary
get router info bgp neighbors
# OSPF
get router info ospf status
get router info ospf interface
get router info ospf neighbor
get router info ospf database brief
get router info ospf database summary lsa|self-originate|adv-router
get router info ospf database self-originate|adv-router
get router info ospf database router lsa

In order to advertise non-local routes to BGP peers, it's required to define them in the local routing table as blackhole

 config router bgp
  config network
   edit 0
    set prefix 10.0.0.0/8
  end
 end
 config router static
  edit 0
   set dst 10.0.0.0 255.0.0.0
   set blackhole enable
  next
 end

Redistribute default route (cisco default-information originate | neighbor xxx default-originate)

 config router ospf
  set default-information-originate enable
 config router bgp
   config neighbor
     set capability-default-originate enable

Influence outbound routing preference

 config router map
  edit ISP1-pref
  config rule
   edit 10
    set set-local-preference 50
   end
  end
 config router bgp
  config neighbor
   edit 200.0.0.1
    set route-map-out ISP1-pref
   end
 end

Once done doing your changes, restart the routing process

exec router clear bgp ip 200.0.0.1 soft out
exec router clear ospf process
