Solstice X.25 9.2 Administration Guide

Routing

In x25tool, you can configure the routing parameters in the Routing window, which can be accessed through the Services menu.

The parameter values are stored in the configuration file: /etc/opt/SUNWconn/x25/routes.

If you have multiple links, Solstice X.25 automatically selects a link for outgoing calls based on address information in a Call Request packet. The parameters for configuring this are:

Route Type

Table 7-9 lists the available route types:

Table 7-9 Route Types


Type	Meaning
X.121 Host	Associates the complete X.121 address of a remote host with a link. This type of entry can include a MAC address.
X.121 Prefix	Associates the leading digits (one or more) of an X.121 address with a link. This type of entry can include a MAC address.
X.121 Default	Contains a link and an optional MAC address. This entry (there can be only one) is used if no match is found between a called address and any X.121 host or prefix entries.
AEF Host	Associates the complete extended address (such as an OSI NSAP address) of a remote host with a link. This type of entry can include an X.121 address or a MAC address, and a protocol id.
AEF Prefix	Associates the leading digits (one or more) of an extended address with a link. This type of entry can include an X.121 address or a MAC address, and a protocol id.
AEF Default	Contains a link and, optionally, an X.121 or a MAC address, and a protocol id. This entry (there can be only one) is used if no match is found between a called address and any AEF host or prefix entries.

Link Number

The link number to be associated with a host address, an address prefix, or a default entry. This is the same number as you specified it in the Link Number item in the Link Editor window in x25tool.

X.121 Address

For an X.121 host-type entry, enter a complete X.121 host address, as it would be specified in the called address portion of a Call Request packet. For an X.121 prefix-type entry, enter the leading digits (for example, the DNIC) of an X.121 address. For the optional portion of an AEF routing entry, enter a complete X.121 address.

Address Extension

For an AEF host-type entry, enter a complete extended address, such as an OSI NSAP address. For an AEF prefix-type entry, enter the leading digits (at least one) of an extended address.

Protocol ID

A protocol id of no more than five bytes (10 decimal digits). A protocol id is an optional addition to an AEF host, prefix, or default entry. Enter a protocol id as a string of consecutive digits.

MAC Address

The MAC address to which the call will be routed if the link is a LAN link.

Enter a six-byte (twelve-digit) hexadecimal value, such as an Ethernet or FDDI address. You can enter the address as consecutive digits or with colons separating bytes. For example, both 080020110233 and 08:0:20:11:2:33 are valid entries. When you save a routing entry with a colon-delimited MAC address, x25tool removes and subsequently displays the address without colons and with leading zeroes within bytes.

Telephone Number

Used for dial-up configurations, this is the telephone number of the point of attachment to the PSDN. In most cases, this is a modem.
