Appendix B

Interoperability

This appendix describes Version 5 and Version 10.0 interoperability issues that

may be of concern to you, depending on the current conﬁguration of your Version

5 routers. The interoperability issues are

• X.25 certiﬁability of Version 5 routers

• Point-to-point connections over a synchronous line

• PPP Version 10.0 compatibility with previous versions

• PPP software incompatibilities

• AppleTalk OUI values for routing over SMDS or Frame Relay

Verifying X.25 Certiﬁability

If you are conﬁguring your router to run X.25, refer to Table B-1, then read this

section.

Table B-1. Conﬁguring a Router to Run X.25

Router Software

Version

Action

Version 7.60 or earlier The behavior of the serial controller chips on link modules

differs slightly from the X.25 standard, making them

noncertiﬁable in X.25 networks.

Version 7.60 or later The MK Thompson 5025 serial controller chip in the link

modules now performs the LAPB function of X.25. This

change signiﬁcantly improves performance. However, you

may still need to replace some link modules that have earlier

versions of the MK5025 chip set to ensure that the router

passes X.25 certiﬁcation.
