527 * IP Addresses ('<em><dst-ip-addr>/<width></em>',
528 * '<em><next-hop-ip-addr></em>' and '<em><adj-hop-ip-addr></em>')
529 * can be IPv4 or IPv6, but all must be of the same form in a single
530 * command. To display the current set of routes, use the commands
531 * '<em>show ip fib</em>' and '<em>show ip6 fib</em>'.
534 * Example of how to add a straight forward static route:
535 * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
536 * Example of how to delete a straight forward static route:
537 * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
538 * Mainly for route add/del performance testing, one can add or delete
539 * multiple routes by adding 'count N' to the previous item:
540 * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
541 * Add multiple routes for the same destination to create equal-cost multipath:
542 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
543 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}
544 * For unequal-cost multipath, specify the desired weights. This
545 * combination of weights results in 3/4 of the traffic following the
546 * second path, 1/4 following the first path:
547 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1}
548 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3}
