563 * IP Addresses ('<em><dst-ip-addr>/<width></em>',
564 * '<em><next-hop-ip-addr></em>' and '<em><adj-hop-ip-addr></em>')

566 * command. To display the current set of routes, use the commands
567 * '<em>show ip fib</em>' and '<em>show ip6 fib</em>'.
570 * Example of how to add a straight forward static route:
571 * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
572 * Example of how to delete a straight forward static route:
573 * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
574 * Mainly for route add/del performance testing, one can add or delete
575 * multiple routes by adding 'count N' to the previous item:
576 * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
577 * Add multiple routes for the same destination to create equal-cost multipath:
578 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
579 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}
580 * For unequal-cost multipath, specify the desired weights. This
581 * combination of weights results in 3/4 of the traffic following the
582 * second path, 1/4 following the first path:
583 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1}
584 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3}
