Enterprise Extender Support for HPR over IP
Enterprise Extender support for HPR over IP allows HPR/APPN applications to run
over an IP backbone network and still take advantage of APPN Class of Service.
HPR over IP encapsulates HPR data into a UDP/IP packet for delivery over the IP
network.
Supported DLCs
Table 2 shows the DLC ports supported by the device over APPN:

Notes:
1. * This column refers to the port providing the connection to the downstream PU
(DSPU).
2. ** Use bridged format when you have two devices connected by frame relay
and one of them does not have APPN. Otherwise, use routed format because of
improved performance.
3. *** Since APPN runs over DLSw and DLSw runs over X.25, you can route
APPN ISR traffic over X.25 by running APPN over DLSw.
