X.25 Features
The following pages describe configuring some of the most common X.25
features on the V!CAS such as:
How do I configure an X.31 link (X.25 in the D-channel)?
How do I route IP traffic over X.25 with MPX25?
How do I configure X.31 in the B-channel (Case A/Case B)?
How do I configure X.25 access for a host on my LAN?
How do I configure ISDN dialup access for an X.25 partner?
How do I use the V!CAS as a TCP-X.25 bridge?
Special Note: The X.25 Local Interface
In X.25 routing the V!CAS decides where to forward X.25 calls based on
the configured X.25 routes. An X.25 route can lead to a point-to-
multipoint interface such as an ethernet, or a point-to-point interface such
as a dialup ISDN or X.25 network partner. Another option is the V!CAS’
special “local” interface.
This local interface is an internal virtual interface. Here, the X.25 packet
is given to one of the V!CAS’ software processes depending on contents
(user data field) of the X.25 packet. The respective software process may
need to reroute the call in which case the packet is passed back to the low-
er level routing instance. For example, when routing IP traffic over X.25
links (see Multiprotocol routing configuration on page 126).
