Hello everyone,
I saw you can create multiple instances of OSPF in one router.

Could you help me to understand a practical situation when you need that feature?

Thank you

If you are running multiple VRFs, each should have its own instance.

We have an "outside" ospf and an "inside" ospf on our asa firewalls so that the firewalls know the whole picture inside and out, but don't leak things beyond where they're supposed to be.

Please if you don't mind help me figure this out. I have my network serving customers with public IPs. I am running OSPF at the edge and redistributing it into BGP at the core. I also have a management network running on private IPs. I would like to run two seperate OSPF instances for them. Currently all the networks belong to the same OSPF instance.
