You must enable a routing protocol for each VRF instance. This example uses OSPF. 
  
 
	 Procedure
-  
		  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
