OSPF and Fortigate are fairly new to me... I am planning to replace a Cisco Firepower with a Fortigate.
Currently on the Cisco firepower there are two opsf processes configured. One has area id 0 and the other has area-id 10 and both are connected to two different cisco switches. Because of the two ospf processes the areas are separated which means cisco-sw2 doesn't receive any routes from area 10. Since Fortigate doesn't support more than one ospf process I have to find another solution.
How can I prevent Fortigate from distributing learned routes from area 10 to 0 (sw2)?
Current Fortigate config:
fortigate # show router ospf config router ospf set router-id 22.214.171.124 config area edit 0.0.0.0 next edit 0.0.0.10 set type stub next end config ospf-interface edit "clientvpn" set interface "port2.505" set dead-interval 40 set hello-interval 10 next edit "dmvpn" set interface "port2.503" set dead-interval 40 set hello-interval 10 next edit "inside" set interface "inside" set dead-interval 40 set hello-interval 10 next edit "transit" set interface "port2.506" set dead-interval 40 set hello-interval 10 next end config network edit 1 set prefix 10.30.15.0 255.255.255.240 next edit 2 set prefix 10.30.13.0 255.255.255.240 next edit 3 set prefix 10.30.14.0 255.255.255.240 next edit 4 set prefix 10.30.16.0 255.255.255.240 set area 0.0.0.10 next end config redistribute "connected" end config redistribute "static" end config redistribute "rip" end config redistribute "bgp" end config redistribute "isis" end end
I tried it but nothing changes and rechecked the configuration.
"set direction out" doesn't appear in the show config but maybe this is just because it is the default value. I also tested it with set direction in which appeared in the config but again nothing changed...
I believe this output is taken from the Fortigate acting as ABR (on which both areas are configured) and on ABR you are expected to see all the routes from connected networks/areas.
Can you connect to any other device/router in Area 0 and check if they can see the Area10 route?
Yes, that's exactly what i described and try to prevent. Fortigate is the ABR connected to a Cisco switch (cisco-sw1) in area 10 and a Cisco switch (cisco-sw2) in area 0.
On the Cisco switch cisco-sw2 in area 0 I can see all the routes from the cisco-sw1 from area 0 and that's what I try to prevent. Forti is distributing all routes from area 10 to area 0 and I somehow need to stop this behavior.
