The RouteOptions attribute is useful only when the default gateway is your own host.
For example, if the default gateway and hme0 are both set to 10.128.8.42, the output of the netstat -rn command resembles:
Destination Gateway Flags Ref Use Interface
---------------- ----------------- ----- ----- ------ ---------
10.0.0.0 10.128.8.42 U 1 2408 hme0
224.0.0.0 10.128.8.42 U 1 0 hme0
default 10.128.8.42 UG 1 2402 hme0
127.0.0.1 127.0.0.1 UH 54 44249 lo0
If the RouteOptions attribute is not set and hme0 fails, the MultiNICA agent migrates the base IP address to another NIC (such as qfe0). The default route is no longer configured because it was associated with hme0. The display resembles:
Destination Gateway Flags Ref Use Interface
---------------- ----------------- ----- ----- ------ ---------
10.0.0.0 10.128.8.42 U 1 2408 qfe0
224.0.0.0 10.128.8.42 U 1 0 qfe0
127.0.0.1 127.0.0.1 UH 54 44249 lo0
If the RouteOptions attribute defines the default route, the default route is reconfigured on the system. For example:
