Configure a Locally Switched PVC
You can configure an X.25 PVC in the X.25 switching software. As a
result, DTEs that require permanent circuits can be connected to
router acting as an X.25 switch and have a properly functioning con-
nection. X.25 resets will be sent to indicate when the circuit comes up
or goes down. Both interfaces must define complementary locally
switched PVCs.

Example: PVC Switching on the Same Router
In this example, a PVC is connected between two serial interfaces on
the same router. In this type of interconnection configuration, the des-
tination interface must be specified along with the PVC number on that
interface. To make a working PVC connection, two commands must
be specified, each pointing to the other.

In global configuration mode, ensure that these TCP sessions remain
connected in the absence of XOT traffic by enabling keepalives:

TCP keepalives also inform a router when an XOT SVCs session is not
active, thus freeing router resources.
