-
-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 senarios, consider displaying a single table or summary mode.

+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
