Usage Guidelines

Use this command to display information about VRFs. Two levels of detail are available; use the brief keyword or no keyword to display concise information, or use the detail keyword to display all information. To display information about all interfaces bound to a particular VRF, or to any VRF, use the interfaces keyword. To display information about VPN IDs assigned to a PE router, use the id keyword.
