X25 interface: incoming QLLC to DLSW and other incoming X25 to XOT session

Hi,

we would like to implement this kind of configuration in order to get DLSW transport for QLLC/X25 traffic and XOT for other X25 traffic:

--

source-bridge ring-group 999

dlsw local-peer peer-id 10.254.37.10

dlsw remote-peer 0 tcp 10.159.1.8

dlsw remote-peer 0 tcp 10.159.1.7

!

interface Serial1/1

encapsulation x25

x25 address 3110212011

x25 map qllc 1000.0000.0001 31104150101

qllc dlsw partner 4000.1611.1234

!

x25 route ^1$ xot 10.111.117.1 10.111.118.1 xot-source Serial1/1

x25 route ^2$ xot 10.111.117.1 10.111.118.1 xot-source Serial1/1

--

- Could anyone confirm that QLLC dlsw statement will take precedence over X25 routes?

--

For example:

If QLLC traffic is received on serial 1/1, will it be forwarded out to DLSW in 100% of the case or depending of X25 destination address, could it be routed to XOT peer?

--

I did not find any document on CCO that confirm this even if it seems quite obvious.

--

If someone had some documentation links regarding this, it would be really welcome.

Many thanks.

Regards/Ludovic.

Re: X25 interface: incoming QLLC to DLSW and other incoming X25

hi,

i am not really sure what exactly u want to do.

what i configured is the following:

i have a about 100 x25 enddevice who want to connect

a ibm host via x25/qllc.

but we only have an ip network.

so i did the following:

i connected the x25 enddevice in the branch to a cisco router on a serial interface (enc x25).

then we forward this x25 call over xot to a cisco 7206.

there i forward the xot over a x25 loop on the same router to a x25 interface on which we do a x25 to llc

conversation.

then we forward this llc connection over dlsw to a cannel attached cisco router which has a escon connection to our host.

if you need any further infos - let me know
