Starting a routing process for a VRF

In global configuration mode, enable OSPF for the VRF instance "corporate."
```
device(config)# router ospf vrf corporate
```

Configure the VRF to use OSPF Area 0.

device(config-ospf-router-vrf-corporate)# area 0

(Optional) Configure the VRF to ensure that essential OSPF neighbor state changes are logged, especially in the case of errors.
```
device(config-ospf-router-vrf-corporate)# log adjacency
```
