Routing SNA and IP

Hi everyone,

I have two routers (3620 with IOS 12.2(17a) and 2650 with IOS 12.2(13)T5) on
a dedicated line.

I want to route both IP and SNA for use beetween two IBM AS/400.

No problem with IP, but how i can route SNA ?

Many thanks,

Olivier

You can't because SNA does not have an explicit network address. You can
bridge it while still routing IP. The best way, IMHO would be to use DLSw+
so SNA would go "over" IP and you have to deal with just IP. Also, if
network has a lot of traffic and small bandwidth, consider some QoS because
your session's will have timeout problems (personal expirience, thanks for
asking).

OK so call me a nitpicker, but SNA is in fact routable, and does have
network addresses. It's just that it's not supported on Cisco IOS, you
can't route it on IOS, and so we have to bridge it.

SNA Path Control Layer is perfectly routable, and uses Subarea/Element
instead of Subnet/Host.

SNA Rules!!
