Page 1033 highlights
• On a switch port on which multiple VLANs are assigned to different VRFs, the source MAC address in packets routed on a VRF may not be the same as the MAC address distributed in ARP requests. As a result, security applications running on neighboring routers that check the source MAC address in incoming packets may find that the address does not match the ARP-learned MAC address. • You can assign a static ARP only to a VLAN that is mapped to the default VRF (0) instance. • By default, all VLANs (4096) are associated with the default VRF until you reassign them to a non-default VRF with the ip vrf forwarding command. You can assign up to 4096 VLANs to a non-default VRF instance. • VLANs used with VRF must be Layer 3 VLANs. Layer 2 VLANs can be configured for non-VRF use. Refer to the VLAN chapter for complete information. • All VLAN member ports must be removed from a VLAN that you move from one VRF instance to another. Task Command Syntax Assign an interface to a VRF instance. ip vrf forwarding vrf-name Command Mode INTERFACE View VRF instance information To display information about VRF configuration, enter the show ip vrf command. Task Display the interfaces assigned to a VRF instance. To display information on all VRF instances (including the default VRF 0), do not enter a value for vrf-name. Command Syntax Command Mode show ip vrf [vrf-name] EXEC Connect an OSPF process to a VRF instance OSPF routes are supported on all VRF instances. Refer to Chapter 35, Open Shortest Path First (OSPFv2 and OSPFv3) 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.
