544 * '<em><next-hop-ip-addr></em>' and '<em><adj-hop-ip-addr></em>')

546 * command. To display the current set of routes, use the commands
547 * '<em>show ip fib</em>' and '<em>show ip6 fib</em>'.
550 * Example of how to add a straight forward static route:
551 * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
552 * Example of how to delete a straight forward static route:
553 * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
554 * Mainly for route add/del performance testing, one can add or delete
555 * multiple routes by adding 'count N' to the previous item:
556 * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
557 * Add multiple routes for the same destination to create equal-cost multipath:
558 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
559 * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}

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