The priority of the routing

As we know, there are many choices according to your requirement in the routing settings. As the following Table 8-3
indicates, the smaller priority sequence would be executed first when running routing policy.

WAN
4. Default Route
Method a means the network which is attached to the interface. There is an example as
the Line-2 at the Figure 8-2. Method b means the network which is defined by the static
route (please refer section 8.4.1) or learned from RIP method. Please notice the method
b is only for LAN/DMZ. Please refer the Line-1 at the Figure 8-2.
The priority between RIP route and static route depends on its prefix. Whose prefix is
shortest, it will have the high priority.
Ex. The 210.10.1.0/24 has the higher priority then 210.10.1.1.0/16.
The defined policy routing as section 8.4.2 indicated. There is an example as the Line-3
at the Figure 8-2.We can notices that policy route only work at the default WAN link.
It is the same as method b of Priority. But this priority is only designated for WAN
ports.
Basically, if no other routing policy has been set, the traffic will go through the default
route. Please refer the Line-4 in the Figure 8-2.
