connection establishment fails, the next destination will be tried. Up to
six XOT destination addresses can be entered.

To configure an XOT route with alternate addresses, thus adding it to
the X.25 routing table, type (in global configuration mode):

x25 route [

#position

]

x121-address

[cud

pattern

]

ip

ip-address

[

ip-address2

... [

ip-

address6

]]

The sequence of alternate destination XOT host addresses is simply
added to the normal XOT route configuration command.

Note:

It can take up to 50 seconds to try an alternate route due
to TCP timings.

Configure CMNS
Routing

The Connection-Mode Network Service (CMNS) provides a mecha
nism through which local X.25 switching can be extended to nonserial
media through the use of OSI-based NSAP addresses. This implemen-
tation runs packet-level X.25 over frame-level LLC2.

The AI2524 CMNS implementation allows LAN-based OSI re
sources, such as a DTE host and a Sun workstation, to be intercon-
nected to each other via the router's LAN interfaces and to a remot
OSI-based DTE through a WAN interface using, for example, an X.25
Packet-Switched Network (PSN).

Note:

CMNS is implicitly enabled whenever an X.25
encapsulation is included with a serial interfac
configuration.

All local mapping is performed by the static mapping of MAC ad-
dresses and X.121 addresses to NSAP addresses.

Implementing CMNS routing involves completing these tasks:

face:
