4.8 Sorting Policy-Based Routes
The following examples illustrate some of the rules according to which policy-based
routes are automatically sorted.
4.8.1 Sorting IP Addresses
"Name" "Routing Target" "Destination Address" "Protocol"
Policy_1 eth0 10.10.10.10/32 TCP
Policy_2 eth7 10.10.10.0/24 TCP
Policy_3 eth6 0.0.0.0/0 TCP
Policy_1 takes priority over Policy_2 because the destination IP address describes
a specific host and not a whole network. Policy_2 takes priority over Policy_3
because the destination IP address describes a whole network and does not match
everything such as the destination IP address in Policy_3.
4.8.2 Sorting Ports and IP Addresses
"Name" "Routing Target" "Protocol" "Source Ports"
Policy_1 eth0 TCP 63
Policy_2 eth7 TCP 60-80
Policy_3 eth6 TCP 61-81
Policy_4 eth7 TCP 60-81
Policy_1 takes priority over Policy_2 because a single port is more specific than a
port range. Policy_2 takes priority over Policy_3 because a lower start port num-
