S-Series: number of OSPF processes for 24 VRFs

[htw]

Hi,
S-Series S180, S140 support up to 256 VRF. We would need about 24 of them and want to use OSPF.
S-Series CLI guide states: "Multiple OSPF processes (process-id) are allowed per router. The S- K- and 7100-Series routers support 4 OSPF processes per VRF and 16 OSPF processes per router."

Does that mean we can use OSPF only in 16 VRFs? Or can one OSPF process be used for multiple VFRs?

Hmm, then what can we do when we want to route in more than 16 VRFs? Use IS-IS? Does such an limit also exist for IS-IS?

One OSPF process can be used in one VRF only.
