Displays the IP routing table for the VRF you specify.
Use this command to display information about the per-user static
routes installed in the downstream VRF.
Displays information about all of the VRFs configured on the
router, including the downstream VRF for each associated VAI.
Displays detailed information about the VRF you specify,
including all of the VAIs associated with the VRF.
If you do not specify a value for vrf-name, detailed information
about all of the VRFs configured on the router appears, including
