• Internet pseudointerfaces, each with its own IP address, network mask, and

broadcast mask:

SEA

SEA0

SEA1

SEA254

SEB255

To extend routing, follow these steps:

1. Deﬁne the pseudointerfaces using the SET INTERFACE and SET

CONFIGURATION INTERFACE commands:

TCPIP> SET NOINTERFACE interface

TCPIP> SET INTERFACE interface /HOST=host -

_TCPIP> /NETWORK_MASK=mask /BROADCAST_MASK=b_mask

TCPIP> SET CONFIGURATION INTERFACE interface /HOST=host -

_TCPIP> /NETWORK_MASK=mask /BROADCAST_MASK=b_mask

For example, to specify the pseudointerface FFA0 on host KESTREL, with

network mask 255.255.0.0 and broadcast mask to 128.30.0.0, enter:

TCPIP> SET NOINTERFACE FFA0

TCPIP> SET INTERFACE FFA0 /HOST=KESTREL /NETWORK_MASK=255.255.0.0 -

_TCPIP> /BROADCAST_MASK=128.30.0.0

2. Enter the same information into the conﬁguration database to set up the

interfaces at startup. For example:

TCPIP> SET CONFIGURATION INTERFACE FFA0 /HOST=KESTREL -

_TCPIP> /NETWORK_MASK=255.255.0.0 /BROADCAST_MASK=128.30.0.0

To display information about the network interfaces, use the SHOW

INTERFACE command. To remove the interface from the conﬁguration

database, use the SET CONFIGURATION NOINTERFACE command.

4.4.4 Interface Routes

If you have a conﬁguration in which multiple networks share the same physical

LAN, you can communicate directly with hosts in other networks without the

need of a pseudointerface for each network.

You can use a broadcast address to designate an interface route, also called a

metric 0 route.

To create interface routes, follow these steps:

1. As the gateway for the route, enter either one of the host’s own addresses or

the broadcast address associated with an interface.

TCP/IP Services recognizes this route as an interface route.

2. Conﬁgure the hosts in the other network to recognize that your network is

present on their LAN.
