Chapter 12 Policy and Static Routes
Table 67 Network > Routing > Policy Route > Edit (continued)
LABEL | DESCRIPTION |
Bandwidth | This allows you to allocate bandwidth to a route and prioritize traffic that matches |
Shaping | the routing policy. |
| You must also enable bandwidth management in the main policy route screen |
| (Network > Routing > Policy Route) in order to apply bandwidth shaping. |
|
|
Maximum | Specify the maximum bandwidth (from 1 to 1048576) allowed for the route in kbps. |
Bandwidth | If you enter 0 here, there is no bandwidth limitation for the route. |
| If the sum of the bandwidths for routes using the same next hop is higher than the |
| actual transmission speed, lower priority traffic may not be sent if higher priority |
| traffic uses all of the actual bandwidth. |
|
|
Bandwidth | Enter a number between 1 and 7 to set the priority for traffic. The smaller the |
Priority | number, the higher the priority. If you set the maximum bandwidth to 0, the |
| bandwidth priority will be changed to 0 after you click OK. That means the route |
| has the highest priority and will get all the bandwidth it needs up to the maximum |
| available. |
| A route with higher priority is given bandwidth before a route with lower priority. |
| If you set routes to have the same priority, then bandwidth is divided equally |
| amongst those routes. |
|
|
Maximize | Select this check box to have the ZyWALL divide up all of the interface’s |
Bandwidth Usage | unallocated and/or unused bandwidth among the policy routes that require |
| bandwidth. Do not select this if you want to reserve bandwidth for traffic that does |
| not match a bandwidth class (see Section 12.2.4 on page 227). |

12.5 IP Static Routes
The ZyWALL has no knowledge of the networks beyond the network that is directly connected to the ZyWALL. For instance, the ZyWALL knows about network N2 in the following figure through gateway R1. However, the ZyWALL is unable to route a packet to network N3 because it doesn't know that there is a route through the same gateway R1 (via gateway R2). Static routes are for you to tell the ZyWALL about the networks beyond the network connected to the ZyWALL directly.
