show ip fib

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

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 of how to display all the IPv4 FIB tables:
