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

541 * command. To display the current set of routes, use the commands
542 * '<em>show ip fib</em>' and '<em>show ip6 fib</em>'.
545 * Example of how to add a straight forward static route:
546 * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
547 * Example of how to delete a straight forward static route:
548 * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
549 * Mainly for route add/del performance testing, one can add or delete
550 * multiple routes by adding 'count N' to the previous item:
551 * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
552 * Add multiple routes for the same destination to create equal-cost multipath:
553 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
554 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}
555 * For unequal-cost multipath, specify the desired weights. This
556 * combination of weights results in 3/4 of the traffic following the
557 * second path, 1/4 following the first path:
558 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1}
559 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3}
