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
