Hello Don,
DLSW has enabled me to pass dozens of LU6.2 APPC sessions throughout my
network with little impact.
1. Yes. Use DLSW Icannotreach sap filters to screen out all but SNA traffic
on your DLSW pipes. You can also use an access-list that will do this on
the remote peers:
access-list 200 permit 0x0000 0x0D0D
then apply this ACL on the peer statement in the remote router:
dlsw remote-peer 0 tcp x.x.x.x {dlsw peer ip addr} lsap-output-list 200
This should help keep all but SNA from hogging the bandwidth.
I run promiscuous peering on my core DLSW routers with icannot reach sap
filters and have the remote router establish the peer via remote peer
statements and the ACL listed above. If you have multiple DLSW core routers
you can also use the backup peer statement on your remote peers; but only if
you are running promiscuous on your core peers.
Hope this helps. Regards, Dennis

DSLw or DSLw+ is the way to encapsulate SNA into an IP packet for
transport across the WAN. It will require you to create a peer connection
form one side of the WAN to a router on the otherside. once this is done
the SNA will be encapsulated into IP for transport to the peer partner. In
setting this up you may want to consider having the router at the remote
location establish the peering connection. That will reduce the cycles on
your main networks router, should a WAN connection, DSU, or interface
fail. You will still need bridging turned on, but will not have to bridge
other protocols unless you need them.
