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
Basic BGP configuration
config router bgp
set as 65100
set router-id 172.16.1.4
config neighbor
edit "172.1.1.1"
set remote-as 65200
set prefix-list-in filter-subnets
next
end
config network
edit 1
set prefix 10.1.0.0 255.255.255.0
next
end
end
config router prefix-list
edit filter-subnets
config rule
edit 1
set prefix 10.1.1.0/16
set action deny
next
edit 2
set prefix 10.0.0.0/8
set action permit
next
end
end
end
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
Troubleshoot dynamic routing
diag ip router ospf|bgp all enable diag ip router ospf|bgp level info diag debug enable
