Altocumulusadvertising route with OSPF on LTM
Hello,
I have to inter-connect a LTM to a cisco router, in that router there is many VRF, each VRF is destinated to a specific client (VRF1, VRF2, VRF3...) in the F5 there are servers every pool of servers are destinated to a sepecific client ( pool1, pool2, pool3...) the idea is to use ospf as a routing protocol to advertise route to different VRF.
if i creat different route domaine and i associate every route domaine to a client, and for each route domain an ospf, how can ospf isolate different instance to have in the final, 1 and only isolated ospf instance for every VRF ??
THANKS
Best regards.

Last time I had to configured OSPF was a long time ago, but I just did some quick research to answer you about this.
So, first thing, to use OSPF in a F5 devices, you need to have Advanced Routing:
https://support.f5.com/csp/article/K14490
That will then use internally a system called ZebOS, that basically uses similar commands as Cisco device. You enter a special shell for that, and from there is just similar Cisco CLI.
In each route domain you create in the F5, you need to enable OSPF for that route domain.
The part I had to research, was how to link OSPF to VRF, as I wasn't sure if was supported. However, looks to be as the documentation talks about that.
"
router ospf vrfUse this command to specify a VRF instance in OSPF. To use this command, you must first create a VRF Name in the NSM using the
command. Associate the same name with the OSPF instance using this command. "ip vrfInteresting the latest version of this document does not document this commands, but I dont think that means that this functionality was removed.
