Cyclades-PR2000 Chapter 9 - Routing Protocols 65 Static Routes Routers used in very small or simple networks may use static routes as the primary routing method. When RIP or OSPF are used, some static routes may still be needed. Configuration of static routes will be explained using two examples. 10.0.0.0 Mask: 255.0.0.0 Router 1 10.0.0.1 10.0.0.2 [...]

For this reason, it is reasonable to prohibit all packets except for those explicitly allowed. This is done by choosing the Default Scope to be Deny . Thus, ALL desired traffic must be expressly allowed by the rule[...]
