(Optional) Display the MAC-IP address information for the specified routing instance.

kernel

(Optional) Display the MAC-IP address entries in the kernel

Flags

MAC IP flags: Identifies : statically installed MAC-IP entries.

  • S—Statically installed MAC-IP entries.

  • D—Dynamic installed MAC-IP address entries.

  • L—Locally learned MAC-IP address entries

  • R— MAC-IP address entries that are learnt from a remote device via the control plane.

  • Lp—Local proxy MAC IP address entries.

    In multihoming networks, a device that learns of a MAC address as a DLR (local and remote) and also learns the MAC-IP address binding remotely will send a MAC-IP address notification message (as if it was generated by traffic). This entry is identified as a local proxy address. The remote multihomed peer identifies the corresponding MAC-IP entry as remote proxy address.

  • Rp—Remote proxy MAC IP address entries. See Lp flag for more information

  • K—MAC-IP address entries that are installed in the kernel.

  • RT—Destination Route that corresponds to an installed entry.

  • AD—Advertised to remote device.

  • NAD—MAC-IP address entries on disabled IRB interfaces. These entries are not advertised.

  • RE—Specifies temporary ARP/ND entries while the device is waiting for a response from an arp or network solicitation request. The entries are removed after three unsuccessful request attempts.

  • RO—Router. This applies only to IPv6 MAC-IP addresses. Refer to RFC 4861 for more information on the Router flag.

  • OV—Override.This applies only to IPv6 MAC-IP addresses. Refer to RFC 4861 for more information on the Override flag.

  • UR—Unresolved MAC-IP address entries. This flag is specific to the Junos EVO environment
  • RTS—Device skipped adding an EVPN Type 2 route in favor of an EVPN Type 5 route with a matching prefix (extensive output displays dest_route_skipped).

Brief, detail

GBP Tag

Assigned Group Based Policy (GBP) from 1 through 65535.

All levels

Logical Interface

The logical interface associated with the routing instance.

Brief, detail

Active Source

The source of the learned MAC-IP address entry. Displays the ESI or router ID.

All levels

Routing Instance

Information on the Routing instance where the MAC-IP address entry was learned.

  • Bridging domain

  • MAC-IP local mask

  • MAC-IP remote mask

  • MAC-IP RPD flags
