Assigning an Interface to a VRF You must enter the ip vrf forwarding command before you configure the IP address or any other setting on an interface. NOTE: You can configure an IP address or subnet on a physical or VLAN interface that overlaps the same IP address or subnet configured on another interface only if the interfaces are assigned to different VRFs. If two interfaces are assigned to the same VRF, you cannot configure overlapping IP subnets or the same IP address on them. Task Assign an interface to a VRF instance. Command Syntax ip vrf forwarding vrfname Command Mode INTERFACE View VRF Instance Information To display information about VRF configuration, enter the show ip vrf command. Task Command Syntax Command Mode Display the interfaces assigned to show ip vrf [vrf-name] a VRF instance. To display information on all VRF instances (including the default VRF 0), do not enter a value for vrf-name. EXEC Assigning an OSPF Process to a VRF Instance OSPF routes are supported on all VRF instances. Refer to Open Shortest Path First (OSPFv2) for complete OSPF configuration information. Assign an OSPF process to a VRF instance . Return to CONFIGURATION mode to enable the OSPF process. The OSPF Process ID is the identifying number assigned to the OSPF process, and the Router ID is the IP address associated with the OSPF process. Task Command Syntax Command Mode Enable the OSPFv2 process globally for a VRF instance. Enter the VRF key word and instance name to tie the OSPF instance to the VRF. All network commands under this OSPF instance are subsequently tied to the VRF instance. process-id range: 0-65535 router ospf process-id vrf vrf name CONFIGURATION Once the OSPF process and the VRF are tied together, the OSPF Process ID cannot be used again in the system. Configuring VRRP on a VRF Instance You can configure the VRRP feature on interfaces that belong to a VRF instance. In a virtualized network that consists of multiple VRFs, various overlay networks can exist on a shared physical infrastructure. Nodes (hosts and servers) that are part of the VRFs can be configured with IP 1024 Virtual Routing and Forwarding (VRF)
