Routing Rules
A rule in the routing rule set can decide which routing table is selected. A routing rule has a number
of filtering properties that are similar to those used in an IP rule. A rule can trigger on a type of
service (HTTP for example) in combination with the specified Source/Destination Interface and
Source/Destination Network.
When looking up routing rules, it is the first matching rule found that is triggered.
Example 4.6. Creating a Routing Rule
In this example, a routing rule called my_routing_rule is created. This will select the routing table MyPBRTable for
any http traffic destined for the network my_network.
