Show IP Fib
=============

Summary/Usage
---------------

show ip fib [summary] [table <*table-id*>] [index <*fib-id*>] [<*ip4-addr*>[/<*mask*>]] [mtrie] [detail]

Description
------------

This command displays the IPv4 FIB Tables (VRF Tables) and the route entries for each table.

.. note:: 
	This command will run for a long time when the FIB tables are comprised of
	millions of entries. For those scenarios, consider displaying a single table or summary mode.

Example Usage
--------------

Show L2fib  
============

Summary/Usage 
------------------

show l2fib [all] | [bd_id <*nn*> | bd_index <*nn*>] [learn | add] | [raw]

Description
------------

This command displays the MAC Address entries of the L2 FIB table. 
Output can be filtered to just get the number of MAC Addresses or display each 
MAC Address for all bridge domains or just a single bridge domain.

Example Usage
--------------
Example of how to display the number of MAC Address entries in the L2 FIB table:


.. code-block:: console

    vpp# **show l2fib**

    3 l2fib entries

    Example of how to display all the MAC Address entries in the L2 FIB table:

    vpp# **show l2fib all**
