- Yes, point-to-point x.25 works. Configure the cisco as an X25-DCE.
- However, you may experience lower delays if you can get PPP to work.

- First, you should turn off the Link Quality Monitoring, use of 32-bit CRC and
- any other PPP-related options on the Wellfleet (I guess you have already done
- that). Set ARP type to "None" in the IP interface definition.
-
- A colleague of mine found out by experimenting the following little apparently
- vital piece of information: on the Wellfleet you have to tell it explicitly
- how it is going to reach the router at the other end of the serial link.
- (Why? Don't ask me.) This is done by defining a so-called "static adjacency",
- which is a special form of a static route, like this:
-
- Static Routes
- Internet Address Type
- ---------------- ----
- 1. 158.36.127.1 Static Adjacency
-
- Configuration Editor
- Internet Address : 158.36.127.1
- Type : Static Adjacency
-
- DLCI : WAN1IP
-
- WAN1IP is the name of the circuit group for the PPP interface on the
- Wellfleet router (the 158.36.127.1 is the IP address on the remote end).
- This is not self-evident, and is not mentioned in the manual (this type of
- static route is only mentioned in connection with Frame Relay). Since this
- is not documented, it may not be the "proper" way to do this, but it solved
- our immediate problem (we have 5.74.2 software on this router -- actually a
- HP-ER router). So: no guarantee...
