OSPF processes for each vdom

[ttaudien]

Hi,

Was wondering how many different OSPF processes a 1200D on 6.4.4 can run, idea is to use one different process id per vdom in NAT mode.

I looked for the hard limit at https://docs.fortinet.com/max-value-table. But there doesn't seem to be any for ospf. I don't know how many total vdom a 1200D can have with additional vdom licenses. But I would imagine the max of VDOMs is much smaller than the max of ospf processes.

Each VDOM would be it's own routing context so one would assume if you ran. 10 vdom and ospf, you would have 10 different ospf-database aka process.

you can execute "get router  info ospf status" to see the process details per vdom and they all are unique but they are called proc0 

e.g

fgt500 (vdf1) # get router  info ospf database br             OSPF Router with ID (0.0.0.1) (Process ID 0, VRF 0)fgt500 (vdf2) # get router  info ospf database br             OSPF Router with ID (0.0.0.2) (Process ID 0, VRF 0)

Different VDOM = independent Fortigate, even by logic there could be no limit on number of OSPF processes. What VDOM license would be worth if we could not run in each VDOM its own OSPF instance?  

Of course not to forget you can have only 1 OSPF process on 1 Fortigate, EXCEPT when we talk about VRFs, but VRFs is such a new feature I am not using/nor have need to on any production Fortigates, so can't say if there is a limit of OSPF processes when VRFs are used.

Each vrf runs it's own ospf-proc also. I believe it's incremented to proc 1 but will have to check. Either way I don't see that being an issue in regards to the customer initial question. Each time you stroke a "config router ospf" and set and router-id that is a ospf proc. I would be more worried on the total number of ipv4 rib entries than any thing regarding ospf-proc, imho.
