The following table is an example of an IP routing table:
Route Destination Subnet Mask Gateway
30.0.0.2 255.255.255.255 30.0.0.10
10.0.0.0 255.255.255.0 10.0.0.138
0.0.0.0 0.0.0.0 20.0.0.10
Depending on the configuration made, the STPro may use an
extended routing table.
In addition to the data contained in an ordinary routing table, it
contains information about the source IP address and the source
subnet mask.
The lookup principle may also be extended: not only the
combination of destination IP address and subnet mask is looked
up, but also the combination of source IP address and subnet
mask.
The extended IP routing table gives extra functionality to the
STPro
and is explained in subsection 12.5.2.
The following table is an example of the STPro extended IP
routing table:
Dest. IP
Address
Dest. Subnet
Mask
Source IP
Address
Source Subnet
Mask
Gateway
30.0.0.2 255.255.255.255 10.0.0.2 255.255.255.255 30.0.0.10
10.0.0.0 255.255.255.0 10.0.0.0 255.255.255.0 10.0.0.138
0.0.0.0 0.0.0.0 10.0.0.0 255.255.255.0 20.0.0.10
