470 * This command is used to add or delete IPv4 or IPv6 routes. All
471 * IP Addresses ('<em><dst-ip-addr>/<width></em>',
472 * '<em><next-hop-ip-addr></em>' and '<em><adj-hop-ip-addr></em>')
473 * can be IPv4 or IPv6, but all must be of the same form in a single
474 * command. To display the current set of routes, use the commands
475 * '<em>show ip fib</em>' and '<em>show ip6 fib</em>'.
478 * Example of how to add a straight forward static route:
479 * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
480 * Example of how to delete a straight forward static route:
481 * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
482 * Mainly for route add/del performance testing, one can add or delete
483 * multiple routes by adding 'count N' to the previous item:
484 * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
485 * Add multiple routes for the same destination to create equal-cost multipath:
486 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
487 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}
488 * For unequal-cost multipath, specify the desired weights. This
489 * combination of weights results in 3/4 of the traffic following the
490 * second path, 1/4 following the first path:
491 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1}
492 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3}
