Adding an IP Route

This procedure is used to add an IP route to the database using the ent-ip-rte command.
The ent-ip-rte command uses these parameters.
:loc – The location of the IP card that the IP route will be assigned to.
:dest – The IP address of the remote host or network.
:submask – The subnet mask of the destination IP address.
:gtwy – The IP address of the gateway or router that will send the IP data to its final destination.
There can be a maximum of 64 IP routes assigned to an IP card.
The EAGLE 5 ISS can contain a maximum of 1024 IP routes.
Ethernet Interfaces A and B on the IP card specified by the loc parameter can be used.
The network portion of the IP address value of the gtwy parameter must be the same as the network
portion of the IP addresses shown for either the A or B interfaces in the rtrv-ip-card output.
The value of the dest and gtwy parameters cannot be 127.x.x.x (the loopback address), 0.0.0.0, or the
IP addresses of the A or B interfaces on the IP card, and cannot be assigned to another IP card.
If the dest parameter value represents a host IP address, the value for the submask parameter must
be 255.255.255.255. Otherwise, the submask parameter value is identifies the network/host ID portions
that must be entered when the dest parameter value represents a network address.
The submask is applied to the IP address which is being routed to see if it yields a route match. For
example, if IP address 192.1.1.2 is being routed and the IP routing table contains these entries.

Table 50: Sample IP Routing Table

IP address
191.1.0.0
192.0.0.0
IP routing occurs as follows:
1. The subnet mask of route 1 (255.255.0.0) is applied to the IP address being routed (192.1.1.2) with
the resulting IP address of 192.1.0.0. IP address 192.1.0.0 does not match IP address 191.1.0.0 in the
IP routing table, so the next route is chosen.
2. The subnet mask of route 2 (255.0.0.0) is applied to the IP address being routed (192.1.1.2) with the
resulting IP address of 192.0.0.0 which matches the second route in the IP routing table, so this
route is selected for routing this datagram.
