589 * Example of how to add a straight forward static route:
590 * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
591 * Example of how to delete a straight forward static route:
592 * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
593 * Mainly for route add/del performance testing, one can add or delete
594 * multiple routes by adding 'count N' to the previous item:
595 * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
596 * Add multiple routes for the same destination to create equal-cost multipath:
597 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
598 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}

600 * combination of weights results in 3/4 of the traffic following the
601 * second path, 1/4 following the first path:
602 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1}
603 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3}
