Upgrading Routers from Version 5 to Version 10.0

B-2

Follow these guidelines to ensure that you are using a link module that can pass

X.25 certiﬁcation:

• Do not upgrade AFN hardware.

• Do not replace link modules delivered after June 1992.

• Upgrade link modules directly attached to the X.25 network that were

delivered before October 1991.

• Inspect only the link modules directly attached to the X.25 network that were

delivered between October 1991 and June 1992. Determine which modules to

replace by removing the link module from the router and reading the revision

level of any MK5025 chip on that module. If the revision level is C03 or later,

do not replace.

Conﬁguring Point-to-Point over a Synchronous Line

This section describes how to conﬁgure a point-to-point connection using the

Point-to-Point protocol over a synchronous line between a Version 5 and a Version

10.0 router.

HDLC Local/Remote Address Settings

On Version 5 routers, you must designate an HDLC “local address” and “remote

address” at each end of a point-to-point synchronous line. The router at each end

receives packets at the designated local address and send packets to the remote

(destination) address.

For each of these parameters, you use Version 5 NCL to either

• Set an implicit address value of DCE (which the router recognizes as a value

of 0x01) or DTE (0x03).

• Set a unique explicit address value in the hexadecimal range 0x00 to 0x99,

inclusive.

Note: If you need hardware to upgrade your router for X.25 support, order it

from Bay Networks. Specify that the router needs this hardware to satisfy X.25

certiﬁcation requirements.
