Dell S4048T User Manual

VRF supports route redistribution between routing protocols (including static routes) only when the routes are
within the same VRF.
Dell Networking OS uses both the VRF name and VRF ID to manage VRF instances. The VRF name and VRF ID
number are assigned using the ip vrf command. The VRF ID is displayed in show ip vrf command output.
The VRF ID is not exchanged between routers. VRF IDs are local to a router.
VRF supports some routing protocols only on the default VRF (default-vrf) instance. Table 1 displays the
software features supported in VRF and whether they are supported on all VRF instances or only the default
VRF.
