How to add protocol ospf to Virtual Router of type VPN-VRF?

[Intersvyaz_Inte]

create vr "CAMPUS" type vpn-vrf vr "VR-Default"
configure vr "CAMPUS" add protocol ospf
Error: Protocol ospf cannot be configured on Virtual Router of type VPN VRF

I need it to be vpn-vrf for our MP-BGP network and I need ospf there, no in default or other vr.

OSPF cannot be add in VPN-VRF since its intended for L3-VPN.
In VPN VRF packets will carry with RT & RD through BGP community attribute.
OSPF doesn't have this capability & BGP can accommodate large volume of routes.
So BGP is used in VPN VRF.

I'm not sure about other vendors but in EXOS we don't have this capability.

From my understanding we cant do it in EXOS.
In 16.1.1 users guide you can refer L3VPN limitations.
Page no.1509.

"OSPFv2 and ISIS for PE – CE peering routing protocol."

But on other vendors it is possible to add IGP protocol to VRF. (Cisco, Juniper and so on).

Construction like "router ospf 1000 vrf CAMPUS" allows to run ospf proccess on Cisco routers in vrf.

Any equivalent in EXOS? How can I isolate one network segment with IGP protocol in L3VPN using Extreme products?
