www.dell.com | support.dell.com Enable VRF VRF is enabled by default when VRF microcode is loaded on an E-Series ExaScale or TeraScale router. On an E-Series router, Dell Force10 VRF supports up to 15 VRF instances: 1 to 14 and the default VRF (0). A VRF name is not exchanged between routers. VRF IDs are local to a router. The following features and functionality are supported only on the default VRF (0) instance: • ISIS • BGP • RIP • IPv6 • Multicast • Static ARP Task Create a non-default VRF instance by specifying a name and VRF ID number, and enter VRF configuration mode. The default VRF 0 is automatically configured when a router with VRF loaded in CAM boots up. Command Syntax Command Mode ip vrf vrf-name vrf-id VRF ID range: 1 to 14 and 0 (default VRF) CONFIGURATION Note: Starting in FTOS 8.4.2.1, when VRF microcode is loaded on a E-Series ExaScale or TeraScale router, the ip vrf [ default-vlan| vrf-name] command is deprecated, and is replaced by the ip vrf vrf-name vrf-id command. The ip vrf-vlan-block, start-vlan-id default-vrf, and start-vlan-id vlan-start-id commands are also deprecated. Assign 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: Starting in release 8.4.1.0, 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. When you assign a VLAN interface to a VRF instance, the following conditions apply: • VLANs assigned to the same VRF have the same MAC address. VLANs assigned to different VRFs have different MAC addresses. The last four bits of a VLAN's MAC address correspond to the VRF ID configured with the ip vrf command. 1032 | Virtual Routing and Forwarding (VRF)
