You can configure each VRF instance as a separate router, this means that you can configure different routing protocols and associated parameters for each instance. You can associate non0 VRF instances with ports.
The port parameters that you can edit for a VRF instance depend on whether the port belongs to only one, or more than one, VRF instance. For example, if a port belongs to only one VRF, you can edit the port parameters of the VRF. If a port belongs to more than one VRF instance, you cannot edit the port parameters of that port unless you are accessing the port through the Global Router with read-write-all access. If you do not have read-write-all access, you can only edit the GlobalRouter port parameters. If a port belongs to a single non0 VRF, the port parameters can be changed by this VRF. If a port belongs to multiple VRF instances, only a user with read-write-all access who is accessing the port through the Global Router can change this port configuration.
