- * This command is used to add or delete IPv4 or IPv6 routes. All

- * can be IPv4 or IPv6, but all must be of the same form in a single
- * command. To display the current set of routes, use the commands
- * '<em>show ip fib</em>' and '<em>show ip6 fib</em>'.
- *
- * @cliexpar
- * Example of how to add a straight forward static route:
- * @cliexcmd{ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
- * Example of how to delete a straight forward static route:
- * @cliexcmd{ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0}
- * Mainly for route add/del performance testing, one can add or delete
- * multiple routes by adding 'count N' to the previous item:
- * @cliexcmd{ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0}
- * Add multiple routes for the same destination to create equal-cost multipath:
- * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0}
- * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0}
- * For unequal-cost multipath, specify the desired weights. This
- * combination of weights results in 3/4 of the traffic following the
- * second path, 1/4 following the first path:
- * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1}
- * @cliexcmd{ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3}
- * To add a route to a particular FIB table (VRF), use:
- * @cliexcmd{ip route add 172.16.24.0/24 table 7 via GigabitEthernet2/0/0}
